Stallones, if you have a similar gun, would you be willing to share a picture of the side and the floor plate? I can post them if need be.
At first glance, the I-B gun doesn't seem so unusual. The frame does have the point engraved at the rear of the frame... but the engraving does not outline the frame. It also has some extra scroll. The breech ball engraving is different. The floor plate looks amazingly similar to an Ideal grade Smith. It's not like other 1 or 1&1/2's that I own or have seen. Maybe I just haven't looked at enough of them. That's what I'm trying to figure out.
I have an interest in early engravers and their connections to different gun companies. Hope to put something together in the future on the subject.
I just thought that a few Ithaca fans might like to add the pics to their own files while still available.
Thanks for the responses, everyone.
