-SG- The earliest Maintenance Instructions in Ian's collection are contained in a small booklet, covering the 16H, Big Four and Model 9. It also incorporates SV tuning instructions by D R O'Donovan. I initially though this dated from 1921 but reading the text with more care, I see it states: 'Our Liverpool agent, Victor Horsman ... finished 1st in the 500cc class in the 500 mile race at Brooklands last year.' The event referred to was actually held in July 1921, so this booklet must date from 1922. Thanks as always to Ian for the loan!
