He handed me the user's manual...no fun at all!

The instructions were
auf Deutsch, ja?
In further support of the "the rewind lever was the problem" theory, I'm now about 1/3d of the way through the roll. One hopes that my sacrifice of one roll of Tri-X will prove to be sufficient propitiation for the Camera Gods, and they'll let me play with, and learn from, this neat old Japanese rangefinder.
The exposure system is already causing some learnin' to happen. It's not TTL, so composition and exposure setting are orthogonal to each other. I've never used an exposure value system before. It's different, kind of like the difference between mens' and womens' pants sizing. The shutter speed and f-stop are oddly linked, through a "Shutter Speed Control Ring" that links the two, advancing one while simultaneously reducing the other so as to keep the same EV. As the name suggests, the idea was that the photographer would use this to set the shutter speed for motion or whatever, and the aperture would change in response. Sort of a primitive shutter priority system, but all mechanical. And, as if all that weren't weird enough, the "Shutter Speed Control Ring" hath not detents... it's continuous.
All this combines to make me think about exposure in a different way.
