The pertinent part of the story is:
Bobby Locke's Putter on Show
15 March 2001
Sydney’s unique Australian Historic Golf Trust Museum may soon boast one of the world’s most famous clubs in its rapidly expanding collection - Bobby Locke’s putter.
The Museum, which is housed above the Golf Mart store at Granville, in Sydney’s west, has been promised Locke’s putter by a Sydney doctor, who was a lifelong friend of the South African champion, rated one of the world’s best golfers and arguably the best putter in the history of the game. Tom Moore, the president of the Golf Collectors Society of Australia, a non-profit organisation which operates the museum, inspected the putter when the owner produced it at a recent Hickory Shaft event at Bowral and has no doubt it is authentic. The owner is keen for the wooden -shafted club, which Locke used all of his career (winning four British Opens and 15 times in the US in three years), to have a worthy setting and he can be assured this will be the case at the Australian Historic Golf Trust Museum.
I will try to contact Mr Moore or the GCSA and see what they say.
Cheers!
