I have a Stevens 12 gauge shotgun that I inherited when my Father passed away a couple of years ago. The only marks on the gun is a serial number H18XXX and on one of the barrels it has 12 ga. This gun has no other markings as to what model it is. It is a double barrel 12 gauge. I would like to clean it up and put a stock on it. But I cannot figure out what model it is. I would appreciate any help that I can get.

Thank you
Charlie
