Released sometime after 1993. This version medium format only. However the AE and AEL setting have replaced the symbols used in the first version for Auto Exposure and Auto Exposure Lock. They also tend to have a 311,xxx or higher serial number.
Model lll came in the war years also and differs in that it has a complex flash delay on the front standard of the lens and serial No,s often in the 22,xxx range. Lenses and shutters found as in model l, and ll. The special version for 'OO" sized shutters was discontinued. Late war years cameras suffer from chrome quality thinness.
Mamiya 6 Serial Numbers
If you have an M6, note that the frame lines are pretty conservative; a lot of my pictures ended up being farther away than I thought they would be, so I've learned to crowd the frame lines a bit. In the meantime, the Mamiya site isn't too bad, although they did purge the Users Forum of many dissenting opinions or observations about some of the minor defects of the Mamiya 6, like the fact that the serial numbers fall off the lenses or that it's really really easy to rip out the cable release socket (don't ask how I know this!). They also post PDF files of the User's Manuals (like this one for the Mamiya 6) though not of the Handy Pocket Guide with my favorite little guy showing things to avoid with your expensive, serious new M6:
hey, wondering if anybody knows what's going on. i have a mamiya six folder with huge gaps between the frames, so i get only six or seven shots on a roll of 120. i use the knob to advance the film since it looks pretty much automatic. i only use the red window to line up the first shot. i wind it until i can see #1 in the window then i close it and forget about it. is this the way you're supposed to do it? thanks11:05PM, 26 June 2012 PST(permalink)
You usually have to use the red window to line up the frame numbers if there is a red window. I've never seen a camera with one that would lock.i don't have experience with the Mamiya 6, but every folder or other camera I have used with a red window you have to line up the frame numbers in the window.ages ago(permalink)
I have an old Mamiya 6 folder (not sure of the model number, but the serial number is 43298). Frame spacing is a bit erratic, but not as bad as yours. I only use the the red window when loading the film. Once I get to the first frame, I slide the window shut. My Mamiya will automatically stop at the next frame when winding. After you cock the shutter and take a pic, I have to press a little lever next to the eyepiece which will the allow me to advance the film. I'm guessing the advance mechanism in your camera is screwed up. Probably an easy fix though, mechanically, these cameras are really very simple.Originally posted ages ago.

If you line up the film right when loaded, does the numbering through the back window stay in sync with the dial? I just got mine, and one matches with one, two with two, and then it starts stopping short of the numbers when looking through the window.
I recently purchased a GQ GMC-320Plus Geiger Muller Counter, and finally got around to passing it over most of my lenses and actually measuring any lenses that seemed likely to be radioactive. Thus, I'm now listing μSv/h measured front:back in My Lenses page along with partial serial numbers.
So, what is background? Well, it's generally between 0.1μSv/h an 0.2μSv/h in the central USA where I live... although it's not uncommon to see slightly higher numbers due to Radon gas in basements. I'm probably giving many slightly radioactive lenses a pass because the mass of a lens should actually block some background radiation thus giving a lower-than-background number; however, I counted the lens as 0 if it didn't read above background from as close-up as I could get the meter.
Exposure to radiation increases with altitude, and flying in a jet is around 7μSv/h... so don't panic about the lower numbers. Still, there is always some risk with radiation, so keeping a little distance (e.g., at least a few feet) between you and your radioactive lenses while you're not using them is probably smart...
