Western Arms was a subsidiary of Ithaca Gun Manufacturing. Your gun was the "Western Long Range" shotgun. Those guns were sold through Western Auto and Sears. Like many shotguns during that time (pre-1968), they weren't serialized. That should be a 12 gauge side-by-side shotgun with a 26-32 inch barrel, with extractors to pull shells out of the barrel, but not eject them, and could have a single or a double trigger. They were made from 1929-1946.
Values run from $100 to $275 for a gun with a double-trigger, with $25 to $50 more for a single trigger model.
I hope this helps.
