Prototype made from a leftover Mizuno M-100 in black oxide with a SCM crown with Cartier script engraved Scotty Cameron on the heel face. The blade is almost identical to the Mizuno Pro-AM model with the Cartier script Scotty Cameron on the face but with a Cameron crown stamp on the back. This putter has similar dimensions from heel to toe as the M-100 model. However, it has a much thinner flange, about 1/4” wide. Very few of these are know to exist.
