The auctioneer has never seen a "Simmons" drainpipe gunmetal putter before, but the one offered here is very similar to Tom Morris "Drain Pipe" putter from the 1890s, forged by respected cleekmaker Tom Stewart. It was the hope of these round head putters to help the golfer be more consistent by reducing the number of mis-hit putts, the rounded head allowing the putter to slip along the ground and not risk cutting into the ground.
The putter head on this Simmons model is made from gunmetal and is stamped "Simmons." The original shaft measures 36 7/16." The grip has been covered in a sort of grip tape, with a built up portion for the left hand at the butt of the club. It looks like the individual who modified the grip on one of the Crans in this auction also modified this putter. In fact, the auctioneer believes that is the case as both clubs are from the same consignor and have likely been together for decades.
