Drew, you are a good researcher, but some of the info in that article is not correct. Part of editing problems and part of republishing bad info. I don't even remember what was in that article, but here goes on rainbow's question. As a caution, when asking for serial no. info, one needs to give more info on the guns,so if the rainbow person is interested, maybe a gun description and pic would help him.
First gun, 49,850-------could be a single trap, a Batavia Leader, or a couple of others. What is it?
Second gun 2437F---------could be a Batavia Leader, or maybe a Black Beauty Special, or a Paragon. What is it ?
