It would be a part-time grouse and woodcock gun so the volume of shooting would be relatively low. This one has steel barrels and the floral engraving so it sounds like a later production gun but still pre-1920.

Researcher, what do the frames look like on the post 1920 No.1s? I'm a newbie to Ithacas and generally view them as the early "boat" style frame and the later NID frame.
