Whats the value of a Type 38 with Mum, dust cover, cleaning rod and bayonet. Had been sitting in a guys closet for 50 years, had a good bore. It even has part of the original sling, the rest of it must have broke off from being so dry. It had the soldier who brought it back name nicely painted in cursive on the side of the butt stock. I believe it was Kokura arsenal. Im thinking about buying it, but they want $400. Whats it worth?
