We have a long list of Fulton tradename guns here, but that one is new to me.
"WR" may be Wm. Read & Sons, Boston but "Western Special" with "English Fluid Steel" has not been reported as a Wm. Read tradename.
The tradename Fulton's I've seen do have the PAT'D FEB 7 - 1911 mark on the action flats.
