This particular Read pattern was developed because of the necessity to save man
hours and tooling costs. Instead of having to turn the entire length of the projectile
body on a lathe, only the two bourrelets needed to be machined to tolerance. This
projectile is an example of an early bourreleted Read pattern manufactured for a wooden
fuze plug. Note the distinct mold seam running the entire length of the projectile body.
The copper sabot shows excellent rifling impressions from the 3-inch rifle wrought iron
(ordnance) rifle.
