This composite image shows another seldom seen mold. The only marking on the mold is "Shiloh IV" stamped onto the side of the blocks. This mold has a very complicated, "sliding" design, and it is not clear how functional it would have been when brought up to casting temperature. Apparently, Shiloh was a manufacturer of muzzleloading rifles some years ago....presumably molds like this one were manufactured as accessories for their muzzleloading rifles.
