Scott, I had hoped that mine was the only one that had survived. Now I will have to give it a closer examination and see if it has any unique markings. A Romanov double headed eagle would be great.
Seriously, Bill is right, it really is neat. Many different avenues for research and learning about the history and evolution of American double gun shooting are represented in just this one item. The merging of histories of The Chamberlin Cartridge & Target Corp., Hall of Fame shooter Rolla "Pop" Heikes and professional sport celebrity endorsement are great reading.
