I am supposed to go look at a gun. The only thing I was told about the gun is that it says J.P. Gemmer, St. Louis, Mo. on it, it has lots of engraving and that it is a 10g Double.

I knew of JP Gemmer and his ownership of the Hawken Shop from the 1860's through 1915 or so, but am not aware of his double guns. Can anyone shed any light on this, or even better yet, a picture? When I get over there I will take pictures of it, just not sure when that will happen.
