Sarge that’s about the second one of those I’ve ever seen. The other my wife bought for $20 because it didn’t work. Like Colt lockwork SAs do from time to time it had a broken/sear bolt spring. I put a wire spring replacement in it that I had lying in the toolbox and it works perfectly. Main difference being that ours has adjustable sights. I haven’t shot it much, used to loan it out to friends or family who needed a tent gun in bear country. I should get it out and fiddle with it soon.
