Western Field (Late Variation) 410 Single Shot Bolt Action Shotgun Parts

Western Field (Late Variation) 410 Single Shot Bolt Action Shotguns:          Click Here To See - Right Side Close Up Image

Warning: Western Field offered two completely different unmarked model bolt action single shot 410 bore shotguns back in the day which were manufactured by Mossberg. Beware that none of the parts are interchangeable between the two (early and late) variations and you need to notice by sight (on our right side close up image link) the different features of the two variations to determine which variant your shotgun is before you order any parts. Does your shotgun have the small ball operating handle with the large notch in the receiver for the operating handle and the small cocking knob at the rear of the bolt body?
