Artillery 4021 shell Dyer 4.5in.
Rifled artillery projectile, Dyer design, Federal manufacture, bursting shell, "case shot" balls packed in sulfur matrix, rounded nose, lead cup sabot, Dyer zinc time fuze , siege rifle, 4.5 in.
Projectile was manufactured in the Federal arsenals following the invention of Alexander Dyer. The sabot system utilized was an expanding lead cup around the base This pattern features a massive lead sabot with a concave bottom, nose of the shell is rounded. This shell is " case shot", explosive charge with lead balls, and with a time fuze was designed to detonate above the heads of troops in the open field. Lead balls are packed in yellow or sulfur matrix. Fuze employed was a Dyer zinc time fuze, with spanner holes, and without a flange, the time fuze for case shot will have a small opening into the chamber, Jones, Fuzes, pg. 36, left. Projectile measures: diameter 4.4in., length 9.1in. (excluding fuze), weight 24lbs.

Projectile measures: diameter 4.4in., length 9.1in. (excluding fuze), weight not determined. Sabot is partly melted, these were apparently left over after the war, attempts were made to recover the lead by melting, this could be a very dangerous process and the process was abandoned, the shell did not detonate but it did melt the sulfur matrix and the loose balls can be heard rolling around inside. Projectile is disarmed, drill hole through the paper section of the time fuze. Recovered from a cache at Augusta..
