Hi, I was looking through some of my grandpas old guns and came across a Riverside arms Co. SxS 12 gauge shotgun. It is hammerless and has a patent date of Apr. 20 1915 on side. The serial number is 10266. I did a little research and found people saying it is a model 315 and that riverside arms was owned by Stevens. I'm interested if anyone has any information about this shotgun like an approximate manufacture date. I don't think it's worth much but it looks like it would be a blast to shoot.
Thanks,
Cody
