Offered here is an incredibly rare pre-Titleist Classic I Augusta Winner (930 made to celebrate Langer's victory) stamped MIZUNO.

From Vog: Years ago Scotty told me there should be perhaps a handful or two of these. To understand why, you should understand the timing. As soon as Langer won the 93 Masters with an early production Classic I, Scotty was planning on this putter. It was a time to celebrate; Scotty was now on a lot more "maps" (he was already on mine) after the victory, but there was a problem. Mizuno essentially did nothing to promote the victory. Shortly thereafter, Scotty decided to leave the company and continue going doing down the path of having his own company: Cameron Golf International. There just was not much time between having this putter finished and leaving Mizuno. The stamping was solely for the weekly equipment survey done on tour, so Mizuno would get credit for a putter in play. 

Condition is refinished, grade 9.5/10, 35" with green Milled Putters headcover.
