I have an A.J.AUBREY single shot SHOT GUN. On the barrel it says CHOKE BORED, On the top of the barrel it says MFG BY THE MERIDEN FIRE ARMS CO MERIDEN CONN PAT APPLIED FOR. Their isnt any serial numbers or anything. The stock has a duck flying over some marsh grass and the name of the manufacture is A.J. AUBREY. I was wondering what the value is for this shot gun. It is in great shape and the barrel breaks with ease when you push on the lever ! Please help ! Thanks !
