Hey thanks for the responses.
By run time I do mean how long it takes the counter to go from 0 to 50 ft.
The cartridge was defiantly used up, I could see the "exposed" on the last bit of film in the cartridge.
Do you think anything will come out from the film if the motor has been running too fast? Would it just be shot at a higher frame rate?
I was assured by the eBay seller that the camera was tested and in full working order. The shop specialise in selling vintage cameras with good feedback.
@ Samuel Berger - I had no trouble getting the camera to Namibia - I went on a working visa for video along with a carnet. I took the camera in hand luggage with me. I hope the footage comes out as it was a beautiful place - plus I want to use some of the footage in the final film we shot!
Thanks
Joe
