This specimen is the
one usually noted. They were primarily used by the Navy on inland waters.
However some Army use was made. The sabot, which is three and one quarter inches
high is cast on the base of the projectile body which has six ribbed flanges to hold it in
place. They seem to have stayed on the projectile quite well. This specimen
was recovered from Vicksburg, Mississippi. Most of this pattern have been recovered
from Island Number 10 along the Mississippi River in Tennessee.
