I've got one kind of like it that I picked up at the flea market yesterday. It's just like the embossed one, but with the embossed "RC" in a trapezoid done in ACL with a star over it. The makers mark is one that I've seen before but still not sure who it is. It looks like a VR inside of a circle with the left side of the R being part of the V.
I googled it and can't really find who the maker is.
