Here is an odd Frankford arsenal mold. It is marked for 30 caliber, yet has a combination of 30 and 45 caliber cavities; it appears to be in original condition. It was inspected by Ormand M. Lissak.

This unusual 11 cavity 45 caliber mold shows a sliding sprue cutter which can be totally removed from the mold base in order to let the smooth bullets slip out. Can you imagine how difficult it would have been to handle that sprue cutter when it was detached and the temperature of molten lead? Nevertheless, an interesting and high quality arsenal-type tool.
