This putter an integral brass soleplate/backweight. This feature was covered under a 1906 British Patent issued to George Brews. This club shows some wear, but it has its original shaft and grip, and the grip is flat down its entire front and back side. A very neat feature.
This putter is from the Fred X Fry collection. see xxxxx. When writing about this putter, Fry recorded that he thought he bought it at a LA pawn shop for $3 in 1928.
