I found this on the union side of the battlefield but I'm sure there was Cavalry action where this was found. It is 1 7/8" wide at its widest point. It is overall 5 1/2" long. It is beveled on the top side. About 1" from the widest end it took a heavy blow that broke it off. It appears to have some kind of plating on it. The picture that is out of focus shows it to be a hollow ground blade. Any ideas on whether its period correct? It was approx. 8" deep.
