Jim,
Some more infro. Capt Seth Pierre Remington Co. D 11th New York was the father of the acclaimed Western artist Fredric Remington. I am slowly finding out what small arms that the union troops used. Confederate side is another story. For the artillery the 1st Wisconsin Light Atrilley had parrots either 2.9 in or 3in,while the Chicago Mercantile had 3 in Oradance rifles.
