The roll-stamped dog and name with the zig-zag border on the frame is what was shown in the catalogues prior to mid-1915 as the No. 1 1/2. However, the No. 1 1/2 was, in that time period, their lowest grade gun with Damascus barrels. The first place one got Krupp barrels was on the No. 2 Krupp Pigeon. This is another example of Ithaca doing what the customer wanted, even on these lowest grade guns. Perhaps because this gun didn't fit any catalogued grade it wasn't stamped with a number?!?
