Thanks for the information, gentlemen. I went back and got a little more information. 30" barrels. 12 gauge, boxlock w/ decorative sideplates, it looks to me. They called the owner. Choked IC and Skeet. 2 1/2" chambers. He says it is a 1908 gun. I misread the serial number, which is actually 42,769--it is worn. I'll attempt to post pictures here. The one thing I noticed is that some screws have been fussed with, as someone put a screwdriver to them in a way they shouldn't--current owner says it came to him like that. I'll attempt to post some pictures, but that might be beyond my skill.
