Hi, johnwill,
Glad you were able to get it apart. I thought I was having a "senior moment" and would have to dig out mine to be sure how they worked. Those guns were pretty cheaply made, but the big concern is that only that pin stands between the moving bolt and the shooter's face. If it breaks or one forgets to push it in, the shooter gets a face full of bolt. Another version has a turning pin with a latch. If the gun is reassembled and the pin is not turned to the proper position, same thing. It rather surprises me that more has not been written on those, but they never sold well and are pretty uncommon, so I doubt we will see many accidents. Besides, who is there to sue? It is a neat collector's item, though, and one of the less common American pistols.
