This 20-pounder Brooke
projectile variety is seldom seen. It has the letter "D" stamped
into the
copper sabot. Brooke projectiles are turned on a lather to the bore dimensions
required. Note that the lathe marks are clearly visible on the sabot. There
are five ratchets on the sabot, unlike the 10-pounder series. Also the letter
"G" is found stamped on the sabot. A good number of these projectiles have
been recovered from the Atlanta Campaign.
