It looks like an older Lachmiller 4 cavity. The number on the side of the mold is 411. It IS in a SAECO mold box but the box is marked by a previous owner as a 41 cal 220 SWC.. It does look correct but since I have no mold charts other than Lyman I don't know who made it or what it truly is. It is in very good condition. Will try to find a set of handles and possibly see what it does cast. If someone knows this mold please let me know. Thanks skeet028
