William Bussey and Joseh Pinder, both from London, received a British patent (No., 16,593) dated Oct. 23, 1890, that covered this putter head made with a gunmetal blade and steel hosel. This same patent, the seventh ever granted for a golf club, also covers the sewn grip on this club.
According to Bussey and Pinder's patent, the hosel is made as a hollow tube. An approximately 3/8" high extension (boss) atop a very short "neck portion" of the blade fits inside the lower end of the hosel. Once joined, the head and hosel are brazed toether. The shaft is then placed into the regular hollow portion of the hosel where it is "secured therein by means of cement, glue, or other otherwise."
The top of the hosel on this putter has been cleaned, possibly in tandem with resetting the pin to tighten the 33" shaft, which is original. What is interesting is the top of the hosel appears to actually be steel, not iron. (The light oxidation lower on the hosel makes the hosel appear to be iron.)
The sewn grip, as shown in the image, consists of a rectangular piece of leather sewn lengthwise into position on the shaft. This took some engineering or sorts to accomplish, but it made for a long lasting grip that would not come loose and unwind as could happen with a wound grip.
The initials of the owner, "HRM", are crudely engraved onto the shaft, just below the grip. The writing on the back of the head, "Bussey & Co, London, Thistle, Patent Steel Socket," is faint, but there. The gunmetal blade is still in good condition, not all dented up as often happens with gunmetal putters due to the softer-than-iron nature of gunmetal. Overall this putter is a solid example, and of the tens of thousands of golf club patents in existence today, this putter was produced under the 7th golf club patent ever issued—which makes this club one of the first clubs ever produced under a patent in the history of the game. Now that is great history, not just great creativity!
