Mold Identification

[Lonestar22]

A friend of mine acquired this mold. It measures .357". There are no markings. Anyone want to venture a guess as to who made the mold and any other information .

The mold design is similar to 1840-1860s Colt BP revolver molds, many of them were
brass, but the sprue plate design is the same. The boolit looks like a .38 pistol 158 gr
RN, so maybe in the 1890s when these first came out in BP form this was probably for
a .38 Colt or .38 S&W or .38 Long Colt, etc.

Hello, Lonestar22. Interesting mould! No idea who made it, but that hole in side & adjustable threaded pin looks to be a sizer? But push-pin looks a litttle short? If it's larger than boolit..wonder if it's for priming case?
