-SG- One of my Australian friends sent this photo of two pre-1926 gear sets from the regular CS box. One of them (on top in the photo) is the standard set-up with 31/19 final drive, 25/25 second and 19/31 bottom gear. The other (lower set) is the close ratio set used in many 1923-1925 OHV machines - and a few SV ones as well - with first gear in the middle position. 31/19 remains as the final drive pair, 25/25 becomes bottom gear and 28/22 is the pair for second gear in the low gear position.
