I have one also. It has a 40" barrel. 12 ga.
chamber measures 3" from breech face to beginning of forcing cone.
stamped CHOKE BORED on left side of barrel. stamped GENUINE ARMORY STEEL on top of barrel.
Was my Grandpa's when he was young. He gave it to me when I was around 8 - 9 years old. (65 now) It stood taller then me then. (I also have his old ridged 97 pump).
He added the roughly bent homemade galvanized metal trigger guard. Riveted with nails. (And a little off center).
And since Dad wouldn't let me shoot it yet, I re-varnished the wood. (wish I wouldn't have done that now) I also used my wood burning set to add the checkering. (or that) They did not have that as sold.
Stock is short. About 14 1/2" from back of barrel to the back top of the butt plate. Kicks like a mule.
I take it to the trap range once in awhile. Stand with the butt on the ground, haller PULL. bring it up. load it and shoot hitting the bird way out on it's way down. The guy's always get a big kick out of that.
Does yours have a trigger guard? It looks like this one came new without one.
