I question whether the locks are worth anything. I also have a box of miscellaneous back actions and parts I'd gladly give away. I've never found any use for them. Most were mediocre, at best, when new and I can't see anyone going to the effort to make a gun using an inferior lock. As Mr. roller has mentioned, there were very high quality back action locks. I once spent years trying to find a loose one to use on a NE target rifle I'd gotten very cheap because the lock was missing. The trigger guard and butplate might be more useful.
