RLW, at 50% I wouldn't consider the rifle much of a collector unless someone were just collecting calibers. Do all the serial numbers match? Outside of the loose barrel I would say the value would be somewhere around 3 or 4 hundred but I've seen them go for more. About three years ago I saw one s/n 220022, around 65 or 70%, in a pawn shop with a thousand dollar price tag. It sat there for a couple of years and then disappeared, so apparently someone thought it was worth that. Steve
