38 Frames Per Roll? How about 39?

[Obtong]

Without much effort, I routinely get 38 frames per roll of Tri-X on my M6. On my Canon A1 and AE1's I would sometimes get 37 pictures from a roll, never 38. My self-loading Canon A2e would always give me 36 shots per roll.

I accidentally got to 38 on my Canon TX today though it didn't feel like a full wind so I didn't shoot that last frame, I rewound from there in case 37 and 38 unded up overlapped. At first I feared I might have torn it off the roll but it rewound fine.

You only get 38 frames, what a shame!

This was called HP5 "Auto Winder" if I remember correctly. I know that I shot at least one roll of this in Panama Jan-Feb of 1983. Really nice to keep going past 36!

I used it once "back then".
Apart from shotting "blind" past frame 40 or so, which I could have lived with, and cutting the roll in half to fit it on developing reels, which hurt miuch more, the film curled like crazy after developing: I wasn't able to make any contact sheets from it!
