I have sitting in my lap a Westernfield M550K 12ga. shotgun. I cannot seem to find any record of this thing even existing, let alone it's value. Gunbroker.com turned up no hits either, can anyone lend a hand?
Western Field was a house brand for Montgomery Ward. (yes, Wards used to sell guns for those too young to remember). In any case, the Western Field 550 series shotguns were made by Mossberg. IIRC, "K" usually means "short" in Mossberg's naming convention (but I could be wrong about that!).
