I need help identifying the manufacture of two molds and the configuration of a third. The first mold is marked "219". this is the only marking on the mold. It is a 147gr WC as cast at .361. The second is marked "441" I have not used this, but it is a 44 caliber SWC. The third is a modified Lyman 457132. It is modified to nose up. It can be used with modified handles but I do not understand how it is mounted in the Master Caster. Any comments will be appreciated.
