Having a gunsmith do any signifcant amount of work will likely exceed the value of the gun...If you're handy, you can probably scrounge many need parts off some of the auction sites, and do alot yourself, for little cost, assuming there's no major (barrel, bolt, etc.) parts required. Old milsurps are fun, but its real easy to invest way more than they are worth, unless you have a particularly rare or desireable model.
