This c.1880 Tom Dunn putter is a nice club!  It's 37 inch shaft and sheepskin grip are original.  The large "39" stamp on the shaft is consistent with the stamps included on the approximately 150 White Horse Whiskey Clubs that were were once part of the White Horse Whiskey collection. These clubs are recognizable by the large numbers often stamped on the sole. There were ultimately upwards of 150 clubs in this collection, assembled beginning in 1959, and they were all stamped with inventory numbers on their respective soles. This collection was built to promote White Horse Scotch Whiskey, which is blended in Edinburgh, Scotland.  After the collection was assembled, each club was set in a White Horse Whiskey display case that held just 1 club and 1 ball. The displays were given to liquor stores to promote White Horse Scotch Whiskey in America. After a period of time passed, the displays were taken down and the clubs were pretty much scattered to the four winds.

The head measures 5 /2 inches in length, 1 13/16" in width, and only 1 1/16 inches in face depth. the neck whipping is original although missing a small amount at its top and bottom.  

Tom Dunn was a respected clubmaker, and this putter with its attractive head shape demonstrates why.  

Born in 1849, Tom Dunn was the son of Willie Dunn Sr. and brother of Willie Dunn Jr—two of golf's great historic figures.  Tom learned clubmaking from his father and started his own business at North Berwick in 1870. From there his career as a clubmaker and professional was off and running.  He worked at the London Scottish Golf Club of Wimbledon in the autumn of 1870, returned to North Berwick as the custodian of the links in 1881.  He held that position until he returned to London in 1889, to work as the professional for the Tooting Bec golf club.
