OK, I'm back. Neither my Singer nor Greist slant shank button hollers are marked "slant". I guess that came later.
The standard plastic and metal cams are interchangeable. The cams for the Professional Buttonholler are larger and not interchangeable.

The professional button holer is marked straight or slant - you are right the older ones are NOT marked - the ones that are slant are marked slant on the shank holder part
