Eureka shell, brass disc sabot, with Frankfort percussion fuze, ordnance rifle, 3 in.

The Eureka shell with unique brass sabot bolted onto the shell, was patented by Clarence Arrick in 1875. Charles Stafford first patented a sabot system that used either four screws wedging the brass sabot onto a tapered base through a center hole, or a simple bolt to fasten it to the body. He did this while working for the American Projectile Company. Clarence Arrick, a patent attorney working for American Ordnance Company, copied Stafford's idea and added three studs, 120 degrees around the shell base to prevent rotation of the sabot during spin. In the 1875 patent he reversed the studs and cast them on the sabot with matching slots in the shell base. The Eureka has been misidentified as a 'Stafford, the primary difference in the two shells is that Stafford did not have the anti-rotation studs and the Eureka did. Fuze is Frankfort Arsenal percussion fuze and is marked: "N / FA 95" . Shell measures: diameter 2.96 in., length 8.25 in.
