Does it say "Westernfield" or "Western Arms Long Range"? The Western Arms Long Range Double made by Western Arms Corp. a wholly owned subsidiary of Ithaca Gun Co. It was essentially a cheaper version of their Lefever Nitro Special, but made with a malleable iron frame rather than forged steel, and had a plain stock and forearm.
Westernfield was a similar gun made for Montgomery Ward which had some flat-topped rudimentery checkering and some even had ejectors and other options.
Either way, the stock and forearm do not appear original.
