Sharps Model 1852 or 53 slant-breech sporting rifle 1/6 plate ambrotype This union private has his rare weapon across his shoulder. Only 2,240 of these were made. The image once belonged to noted collector John Sickles and was in the Nov/Dec 2000 issue of Military images magazine. There are two hairline cracks in the image. This may be the only chance to own a military image with this rare weapon. Contained in a nice patriotic case.
