I've managed to end up with two 1950's era H-16's, as part of a bad habit called "camera collecting". One with trioptical viewfinder. Best guess is 1954 and 1957-58, based on information when I got them.
I'd like to know where the serial #'s are located; thought it was inside, but the numbers seem too short, based on the resources I've found otherwise.
Might even be inclined to use film again (after a decade of *digital video). *That's where I've spent all my continuing education since about '95;-)
Any links, info, etc. greatly appreciated.
Many thanks!
Christopher
