Federal 12-pounder Bormann Fused Ball
Note the star in the center of the Federal Bormann time fuze, this star signifies manufacture at a particular arsenal. The authors know of several different arsenal marks found on other Bormann time fuzes. This example is non-excavated, and the Bormann time fuze is unpunched. The function of the Bormann time fuze is explained here. A cross-section of a spherical case-shot projectile, fitted with a Bormann time fuze, can be found here.
