Z1654 Confederate 12lb. Polygonal Cavity Spherical Shell
Description: Here is a very nice polygonal cavity shell that has been cleaned and coated. The interior of these shells is segmented and was to break into uniform shapes upon explosion. This one is in very nice shape with very small uniform pitting along with a couple of period dings.
