Hi I just saw a mold today marked B&M-IRON, and the number 452236. This is a single cavity and it is open on the bottom, there is a steel shaft mounted into a wooden handle that fits into the opening. It looks like a standard semi-wad cutter? This mold has handles and is built like a SHERMAN TANK. Anyone know who B&M might be? Did BELDING & MULL make molds? Maybe BALLARD & MARLIN? I've had BOND molds and they were not marked like this any help would be appreciated.
