The Stevens stuff I have read that prior to 1949, they didn't have numbers on a large percentage of their products. Back then they also made Riverside Arms products. I have a Riverside that I was trying to date to no avail. All avenues led to, it's pre 1949. Sucks as it's a single shot 12 gauge and I have no way to determine what shell size it takes. It's a decent old gun I have for sale from a collection, and everytime someone asks me questions the best I can give them is what I said here. I just don't know of any way to further learn about it. Another post I read where a guy talked with Savage about it, they said that they had none of the records from back then anymore.
