Can someone tell me what kind of gun this is
my papaw had it for at least 50 years if not more, he found it in an old barn. It is a .22, the only stamp, marking, numbers or anything to identify it is the letter A on the end of the chamber next to the barrel on the top. You squeeze the handle up and it makes the barrel slide forward to load it/cock it. It will stay forward and open until you pull the trigger then kicks the handle down and the barrel backwards to fire he bullet. To unload the empty shell you have to squeeze the handle back up to the barrel to open the chamber back up and pop the shell out with your finger. It is a little bit smaller than a normal sized .22 that sells today. I hope someone can tell me what this gun is!
