I had a Model 1 until two years ago. Walnut stock (supposedly), black receiver, Williams open sights.
Will have to report back later, as got to go out with the Mrs down town now....It was okay, the major drawback being the very creepy trigger, and they're right little buggers to take to bits to tweak.
I think the pump-up pistol platform is FAR superior.....Doddle to work on, far better trigger (and that trigger is so easy to tweak). You can now buy new, over here, the 1322 pistol, the .22 version of the 1377.
Stick a steel breech conversion on it and shoulder stock and you have yourself a very accurate, recoilless little tool.
