  1. Greetings Duncan! "I just know it's going to be something stupid, like with "MOS Camera"... Close.... 'DOM' is the 1st 3 letters for......... are you ready for this? .... 'DOMestic' Noun: something produced or manufactured in one's own county. Arri USA used 'DOM' exclusively to identify any Arri camera equipment that was designed and manufactured in the USA, not at the main factory in Germany. This was when Arri Germany and Arri USA were separate organisations. The most popular item was the DOM Animation/Time Lapse motor for the 16S and 16M cameras. Way back in the mid '50s, there was an interest in 'single framing' with these 16mm cameras. The cameras were not really designed for single frame operation, but Arri offered this 'lightweight' motor in April 1956... Meanwhile, back in Germany Arri factory made 'The Single Frame Gear'. This unit fit in between the camera and the drive motor. Not very popular in the U.S., in my opinion. So , Arri USA continued making and refining the DOM unit and ended with this version in the late '60s, early '70s. You still had to get a capping shutter which came from Germany. Hope that answers your question... Charlie
  2. Oooops, forgot to add the pic of the NCE motor adaptors........
  3. Greetings Duncan! Your mystery part for the Arri 16 ST (or M) is the 'camera adaptor' for an NCE Animation Motor Drive System for 16mm or 35mm cameras. This single frame motor drive was probably made by Gordon Enterprises. One would purchase the Control Box and motor, then add the appropriatecamera adaptor for the camera or cameras they wanted to use it on. You would still need a 'capping shutter' to use it with the Arri cameras, as those cameras were not really designed to be used for single framing. They could fog the film from light entering the lens when the film was at rest. The controller has provisions for 'synchronized shutter openings' or to use the 'capping shutter'. I've never seen this set up, not even on eBay. Back in 1983, the NCE III Controller and Motor would have set you back $1650, then you add the cost of the camera adaptor. Also, the motor was 120 volts. You would need a long extension cord or a generator to use it in the desert for time-lapse with an intervalometer. Nice looking piece of Arri equipment however! Charlie
  4. Looks like someone made a lens support.... .https://www.ebay.com/itm/185017981152?hash=item2b13ee58e0:g:cuQAAOSwrnRhHpJU
  5. Greetings Tim and Fran! The little wire on the power cord is indeed a grounding wire. It is used to ground the torque motor on the 200ft or 400ft magazines. Arri literature said: "As the magazine is attached to the camera, electrical contact is automatically made." Well, yes and possibly no. In the pic below, the torque motor is attached to the magazine. The torque motor is now grounded to the magazine. When the magazine is attached to the camera body, the magazine is now grounded to the camera body completing the electrical circuit for the little torque motor. The red arrow points to the contact pin on the magazine for the positive 8 or 12 volts from the camera. The exposed metal of the magazine is supposed to ground the magazine to the camera body.... However, possibly in the early days of the magazines, the electrical ground, for some reason, didn't make a complete circuit through the camera. It could be corrosion that caused resistance in the ground circuit reducing the voltage. Arri backed up this possible (sometimes unpredictable) condition by having a little ground wire that plugged into the small, silver socket (see above pic) underneath the motor and then to the neg side of the power cable. This provided a good positive ground for the torque motor. When I 1st started shooting with the 16s and mags, I always used the wire. But after a while I stopped that annoyance and just mounted the mag. I never had any problems. The little grounding wire I used finally disappeared (I do have one left .... just in case). You just forgot about this Tim! lol Charlie
  6. Hello John! Take a look at this site for the 'Museum of Magnetic Sound Recording'. It states that the Webster Wire Recorder was made after the war. A link to the Wire recorders: https://museumofmagneticsoundrecording.org/Wire.html Cheers! Charlie
  7. Greetings Dom! I thought you would find this Arri advert from 1959 informative..... Arriflex Corporation of America made many Arri items for the American market. They called them 'DOM' for 'Domestic'. Charlie
  8. Greetings Hugo! Thank you for posting the pic of your Minolta M and the link to an instruction manual for a Minolta M (n). This helps me solve the confusion of the 6 volt battery, the meter lock switch and the Cine speed of 1/50 at the end of the shutter speed scale. Minolta came out with the model M (n), or version 1 that still had a 6 volt battery. I was not aware of of this version of the M. When I acquired my M, it was the 2nd upgraded version of the M, and had the 1.5 volt AA battery. From your pic, this is the version/model you have. I've copied a couple of pages from my Minolta M instruction manual. Compare these to the same pages in the on-line manual for the Minolta M (n) that you posted a link for....... (the page numbers on my pages match the same pages for the M (n) pages) On page 4 of the manual for the 2nd version of the M (the ones we have), you'll see it does not mention the Cine speed of 1/50 at all. Then look at the on-line manual for page 4. The 'Meter Lock' switch was nothing more than an on/off switch as is on our meters. The Minolta F reinstated that Cine function, apparently enough people complained. So why did Minolta make those changes to the Minolta M meter?? Read the very last sentence on page 19 of the English language manual or the on-line manual you provided. Charlie
  9. Hugo...... Does your meter look like the one in the photo from a catalog? It does say the Auto Meter takes a 6volt battery. Also, it says there were 2 models, analog and digital. The spot meter I had before the Minoltas was a Pentax analog meter. Could you post a pic of your meter?? Charlie
  10. Hello Hugo and Dirk! Hugo, you said: "On my Minolta M Spotmeter when I get to 30m and press the decrease key again, nothing happens..". That's correct, nothing will happen on the Minolta M meter. The model M was the 1st version, and in my opinion the better of the 2 models (the F being the 2nd) for Cine work at the time it was introduced. Yet, the model F was faster to make settings adjustments and figuring the Cine measurements. (seems the model F went to 11) The model M does take one AA battery, 1.5 volt. Here's how to set the meter for Cine measurement... It turned out that the model M was better at reading discontinuous light than the improved model F. So, for me, the model M is more accurate when reading the old TV monitors, projected film on screens and subjects under HMI lights. I used both models. Another thing to think about when using your spotmeter on sets with multiple light sources, you need to shade the meter's lens from stray light. As these meters became popular, small cottage industries popped up making nice slip-on aluminum snoots for the meter...... One had to have a snoot to look cool among the crew members. Charlie
  11. Your motor is the basic Arri 16 S / 16 M Governor Controlled motor that was modified to output a 1 volt sync pulse/signal that was fed to a 1/4 inch synchronous tape recorder. One would plug the sync cable (umbilical cord, as it was called) from the recorder into the single pin RCA jack located on the back of the motor next to the knurled turning knob. Any minor speed variations or fluctuations of the camera would be recorded on the ¼ inch tape. With this motor you could then shoot lip-sync sound with your noisy Arri 16 S (with additional sound coming from the 400 ft torque motor) or M camera (well, maybe the camera was in that user friendly ‘blimp’). You wouldn’t need an A.C. power supply or the Arri a.c. sync motor for sync filming. The camera was driven by batteries and same for the recorder. “Governor controlled motor for 8 V battery operation with fixed camera speed of 24 (Cat. No. 1161) or 25 frames per second (Cat. No. 1162). This speed is automatically maintained and cannot be changed. The speed required should be stated when placing an order. Other speeds can be adjusted on request. This motor is designed for forward drive only, and a knurled knob for turning the camera mechanism by hand is also provided.” Most likely the speed of your motor is 24 fps. You can always check the speed of the motor on the camera with a strobe light. The motor used for this modification was the early Arri Governor Controlled motor. This was the one without the transistor attached to it. I would guess your motor is from the early to late 1960s. The sync pulse modification did not change the operation of the motor. So, now you have a constant speed motor (24 fps) for your 16 S camera. This motor was modified by Magnetic Sales Corp, an equipment division of Loren Ryder’s ‘Ryder Sound Services, Inc’ at the same address. Loren Ryder started his business in 1948. He was an early pioneer in magnetic sound recording for Motion Pictures, initially working for Paramount. He became a leader in the industry for portable magnetic recording on location. https://en.wikipedia.org/wiki/Loren_L._Ryder There is a nice article about him in the May 1973 American Cinematographer.
  12. "Your camera and magazine might need to be connected by a ground wire." Chris, I agree with Jean-Louis's above statement. According to Arri back in the day, the torque motor was grounded to the magazine when locked into place on the mag. When the magazine was attached to the camera, the magazine was supposed to be grounded to the camera. But, back then there must have been occasional problems with grounding the torque motor, so Arri came up with a sure fire solution, ground the torque motor directly to the ground on the battery. This was accomplished with a 'ground wire' as Jean-Louis recommended. When you purchased a 16 S power cable from Arri, it came with a grounding wire for the torque motor. One end of the grounding jumper cable was plugged into the ground side the power cable, and the other end was plugged into the torque motor via the silver receptacle shown in the pic below. 400 ft & 200 ft torque motors have the same grounding connection. The red arrow points to the positive power pin in the magazine that makes contact with the camera. When the cameras were newer, it was rare to use the jumper cable (my experience). I used 4 torque motors and never had problems, or needed to use the cable. Most users removed that little cable from the power cord and set it aside. If you were just using 100ft loads, you didn't need it. Then those little cables would eventually disappear. I've seldom seen them in 16 S kits for sale. Arri listed the ground cable in a 1962 price list: "Special Ground Connection Cable (Replacement); goes from main Cable to Torque Motor". It was still listed in a price list as late as 11/1980. I don't have the separate instruction sheet for the 400ft mag and torque motor. Very little was said by Arri about this ground cable. There are no ad pictures that I've seen showing this little cable in use. Applying 8.4 volts to a torque motor that was modified for 12 volts would just make the torque motor run slower. If the circuit supplying power to the torque motor, and then to ground, is complete, it would still run.
  13. The Canon C-16 Macro Zoom was based on the Academy Award winning Canon K-35 Macro Zoom for 35mm cine format cameras. Cinema Products was the distributor for Canon 35mm professional lenses. A 11/1972 ad.... You focusing problem has to do when you have the lens in Macro mode. When you put the lens in Macro mode, you then focus the image with the Macro ring, not the front focusing ring. Canon 1st advertised the 16mm lens in 12/1972 In 1976, the Canon 12-120 was $450 cheaper than the Angenieux 12-120. However, at that time the Angenieux 12-120 was a more popular lens. The Canon lens never caught on, and I don't think many were sold. Now rare. Rumors were around that the Canon 12-120 wasn't very sharp at the wide end, but very sharp at the long end. Rumors. I never used one, so I can't say, yet I'm repeating rumors.... A sales brochure from early 1973...
  14. Pic 16s with 200 ft mag attached. The 200 ft mag is a 'clam shell' type mag, the lid is hinged at the top. Very useable when hand holding, smaller profile, less weight, than 400 ft mag. Not buffeted around as much as the 400 ft mag on windy days when hand held. Nice for short ends on cores 100ft to 199ft.
  15. From an early sales brochure... Remember, the 400ft torque motor will not work on the 200 ft magazine.
