I just got a single-shot 22LR M-49. It's a cute little lever action, although I kinda wish it was the repeater. Anyway, I've almost got the thing completely apart. The pin that holds the block in won't come out, and the barrel is loose, and the receiver and associated parts look like someone spray painted the thing black... Big blotches of thick paint, even a hair under the paint, and it flakes off very easily. The barrel finish looks OK. What was the original finish? The stock is fairly worn and dirty, but I'm not too worried about it, it's still solid, but I'm thinking of drilling some holes on the top and putting a sliding top over to hold extra ammo. Back to the barrel. How is it removed/replaced, and how do I keep it from moving? Right now it rotates a little too easily, and with the action open it can be pushed into the receiver by maybe 1/8". It won't move more than that or rotate more than 45 degrees in either direction(total 90º play, although some force is needed beyond maybe 10 degrees). And what do I do about the stuck pin? It's the biggest one on the gun at around .375". I would have left it together and played with it, but the guy I got it from is terrible at keeping his toy guns clean(lots of crud out of this one, tons of lint and crud out of a 25 pistol that he said he had never cleaned since he got it), so I like to completely strip them and clean everything thoroughly. Any help would be greatly appreciated.
