This 1/6 plate clear ambrotype is published in my recent book "Civil War Hard Images Volume 2 - Union". I believe this is a New York style state issue jacket with shoulder tabs, a belt loop (his right side) and a breast pocket. He holds an 1842 .69 caliber musket with a socket bayonet at attention. He has a small US belt plate (reversed but with US gilded) and an eagle breast plate attached to his belt (?????). He has either a cap box or a pistol holster on his left side by the round breast plate. The ambrotype is not identified and comes in a 1/2 thermoplastic case. #11229=$550.00
