Depends, if rare and a 1916 isn't, then it might be worth it to do so. If your gun is a fun shooter, then it also might be worth it. But a nice restore will cost $400-$600, so cost of the gun, plus $400+, is it worth it?
To many colelctors, once you "reblue or restore" value as a collectable is dropped in half to a third.
WELCOME to the forum Chuck!!
Can you provide pictures of both sides?
