I also encountered one of his customers at the Imperial meeting at Bisley a few years later. A friend of mine who was acting as range officer on the pistol range beckoned me over saying "you've got to see this".
There was a little Chinese guy at 15 yards shooting a PAA target (gangster target). The chap had on every conceivable type of holster you could imagine. He was like the old Bianchi advert. He would draw a gun and empty it towards the target then let the pistol drop to the floor and pull another pistol from another holster and repeat the process. In all he must have fired over 50 rounds at the target from numerous pistols including a baby Browning.
My mate told me that Tom had sorted him out.
