Shotgut Value-Pls Help

Gents,

I inherited a 12 gauge shotgun from my great grandfather 20 years ago. An avid hunter, I have never fired it. In fact, I never met him either. The gun has few markings. Here is all i have: Patent August 12, 1913 on top the barrel. AM 166 is stamped under the forearm of the gun. Palmetto Arms Co. Philidelphia, PA is stamped on the side. It's a 12 Ga crack barrel w/ a 30" barrel. It may be worth nothing but priceless to me. I know it put many meals on my families plates. Any suggestions? Thanks,

hi saintsfan,
with the information that you have you'ld get the best answer from shotgunworld.com. they should be able to take what you have and give you some info on it. a picture would probly help also. a wall hanger with that kind of meaning is surely priceless.
