A Confederate copy of
the Federal Navy Dahlgren, probably an experimental projectile. The Dahlgren was
not successful, almost always throwing the sabot. The wide, raised,
vertical surfaces are not
pre-engraving, but merely bearing surfaces. Soaped rope packing was used in the
space between the sabot and projectile body. This specimen was
recovered from Vicksburg, Mississippi. This pattern projectile is extremely
rare!
