The Remington Model 12 / Remington>>>R.G.Owen>>>Charles Sheldon>>>Michael Petrov that we have all seen on this forum is the one listed. Michael had another, Remington 12C NRA Target that he had when he was a kid. That rifle he told me would go to his sister or daughter. The R.G.Owen rifle is so unique because he had so much correspondence between Mr. Owen and Mr. Sheldon where the specific rifle was mentioned. Truly thorough and rich provenance.
