Is that what the BA stands for? I was wondering what that could be with JPL underneath it. Where should I look for an import stamp/marking? I've broken the entire gun down so ill scour over it tonight and post anything new I find. I don't want to change anything on it except try and clean up the wood a little bit because there is 60+ years of dirt in it but after reading numerous threads on here some guys have said that improves the value of the gun.
