First off, I know nothing about guns. I can safely handle, load and shoot my hunting rifles, but thats as far as my gun knowledge goes. This gun was just given to me by my Great Uncle who told me to sell it and keep the money as a gift. He said a friend of his claims it hold little value, but never got it checked out. There's markings all over it and from the little googling I did I really didn't find anything other than that this forum is the place to ask. So. Here are all the pictures of the markings. I can provide more picture/information if needed. Any help would be greatly appreciated. Thanks.
