Bob,
I obviously failed to learn from your instruction on these guns a few months ago. I couldn't recall examining this gun for the rotary bolt when I bought it last Friday. They'll send the gun direct to me since I have a C&R, but it isn't in my hands yet. So, I checked the s/n against the bbs's list of production yrs. It looks like this is a 1935-36 gun. So, it's very likely a Fulton.
