James, here's a few of the rough things that typical west hurley thompson needs addressed.
1 Tight chamber
2 Cast magazine catch will make magazines fit poorly and cause jams
3 Cast actuator (poor function)
Various other parts may be cast.
poor machining in the bolt channel.
Pop riveted rear sight will come loose.
1-3 will definitely affect function. The rest to a lessor degree.
If you want to shoot it and keep it, get it working and have lots of fun.
If you want to shoot it once and sell it, you aren't out anything to try it "as is". Some worked ok and had varying degrees of gi good parts.
If you just want money sell it as is and let the next guy worry about it.
