Civil War Tintype 1/4 plate brass & long sword!

Civil War Tintype
Great image with sword & brass buttons

Terrific and original circa 1860's Civil War era tintype of a soldier in uniform holding his long sword. He appears to be a Union soldier and is wearing a full uniform and has a long sword, scabbard, military cap and his jacket has many brass buttons. It measures 3.25" high x 2.75" wide and has a bronze mat. It is in fair condition but has some flaking on the right and is a darker image, see the photos. The back is marked "J.D. Herriott 1862".
