any idea what a gun like this would be worth?
It depends on a lot of factors. When was it made, Who made it, condition, etc. Brand new ones from Springfield armory start at about 1200 dollars, but you can get service grade rifles, meaning they are beaten up and ugly, but functional, for about 550-600 in some places. If you have more specific information about history and condition, I may be able to get you prices of other guns in its category
Problem is idk any of that information, the only thing i know was it was used in World War II, and its still in pretty great condition.
then generally if it is still shootable and not in too bad condish it is worth 600-700 bucks.post some pics so we can see what you are looking at!
prices also vary as to whether or not it was armory re-barreled (as lots of them were)
