Can anyone tell me anything about this shot gun. It was my fathers, and all I know is that it is over 70 years old, but could be much older. Pictures are attached. The only markings I can find on the shotgun are shown. Remington Arms on both sided and the serial number on the triger guard. Someone at one time told me that they believed it had a Dismargus barrel and might be unsafe to fire. All I can see is when I look at it are some squiggley lines or designs that resemble fingerprints. Tried to show this in the picture, but not sure how much you can tell. Would like to know anything you can tell me about this gun, but my primary concern would be if it was safe to fire. I used this gun to hunt when I was about 18 but since then it has simply set in the closet. In other words it has not been used in the last 50 years. As someone pointed out earlier my spelling leaves something to be desired and I am in trouble without a spellchecker, so please excure any errors.
