Yes on it being Montgomery Ward. Western Field was a trade name used on guns sold by Wards. Western Arms Corp. was a company owned by Ithaca Gun Company. A picture and ser# will tell the story. Best bet is Lefever, Nitro Special but could be Western Arms, Long Range Gun. All mfg by Ithaca.

I have a Western Field Deluxe, 16 ga., with ejectors and nice checkering. It is a Nitro Special.
