If you check the FAQ's you should be able to date them, you can always shoot ML or shotgun barrels on them and most likely fit them yourself. Some of the older actions came with .22 Hornet or 30-30 barrels in addittion to a shotgun barrels as a combo and some of the older actions were offered by the company with 45-70, .22 Hornet or 30-30 barrels. Just try any of your current shotgun barrels on those recievers and see if one of them by chance fits. If not there ar those here that can help you with "barrel fitting 101". You can get all the needed info in the FAQ's also....<><....
P.S. it looks as if you are set for your second star (they used to be bullets) after only 7 more posts, a big occurance, but check out Quicks post count, soon to be 10,000!!! No one knows what will happen to the counter since no one has ever had a post count that high, and to think he's one of us, a washashore Handiholic!!!!....<><....
