According to what I could find, they began making these in 1949, on a quick search couldn't find an end date(added: reference just ran across was 1968, after that import banned due to their size). They were chambered in either .22 Short or .22 Long; the one I fired was a Long. The safety is on the left at the front of the grip: up for
This is one of the smallest, lightest pistols I've ever handled, especially for all steel construction. Only my middle finger wrapped around the grip, but recoil wasn't bad at all. Sights are in a groove machined into the top of the slide: a nice square little post in front and a notch in back. If I have a chance to shoot it again I'll try some more precise aiming, the other day it was a chance to put a few rounds through and that was it. The trigger broke a lot more cleanly than I expected, too.
All in all, a very interesting little piece. I'll close with this I found at Unblinking Eye:
I consider these guns curiosities. They are fun to plink with, but can hardly be considered serious self-defense weapons, although if you could throw one hard enough and with sufficient accuracy it would have much the same effect as a rock. Since the safety only locks the connector, I fear the striker could be released if the gun were dropped, so I would not carry one with a round in the chamber.
Nowadays when you can get a .32 in a slightly larger package, this isn't something I'd want to rely on, true enough; it's way down in the 'Any gun is better than no gun(but some are just barely)' rankings.
But it's so damn cute, I want one.
