As Researcher said Ithaca carried the No. 2 Pigeon gun in their catalog until about 1915, however I have never come across a Minier or a Flues that was marked Pigeon Gun on the barrel...only the Lewis model, and not very many of those. The few that I have seen were all in the 73759 range. The Lewis guns that I have encountered had butt plates. I would think that a collector would pay a bit more for the Lewis No. 2 that was marked Pigeon...I know that I did. I would be interested in knowing the serial number of your gun or at least if it is close to the aforementioned range.
