Don't think it's a Fulton Special, Drew. That was basically a dressed-up Fulton, and all the Fultons are very easy to spot because of the 3 screws in the floor plate of the receiver, which this gun does not have. I'm thinking Hunter Special, which was an entirely different (and more expensive) boxlock manufactured for a fairly short period of time, mid to late 1930's. It had a rotary top bolt like the LC Smith; the Fultons did not. However, as I read the serial number, that looks to be about a decade too early for a Hunter Special.
