DIAMETER: 4.50 inches
|This shell is
non-excavated and rests on its original wooden sabot. The wooden cup was designed to align
the fuze and keep it forward and centered in the cannon bore. The cartridge bag was tied
in the deep groove cut into the base of the sabot. The twine was used to tighten down the
four tin straps, holding the sabot and fuze collar more secure. The 12-pounder (4.62-inch
caliber) projectile was the most common Federal shell employing the Bormann time fuze.
This style sabot was designed for the 12-pounder
Napoleon smoothbore cannon.
The example below is a fixed 12-pounder Bormann fuzed ball. This is similar to how fixed-ammunition was manufactured during the Civil War.
