Albion 5 speed close ratio racing cluster from early to mid 50s as fitted to racing Vincent Grey Flash and Manx Nortons. At the time these were the only 5 speed gear clusters available. The cluster fits straight into Albion gearbox cases. It originally came out of the REG 250cc DOHC twin racer that John Surtees won so many races on as well as setting several lap records in the mid 50s.
Although in reasonable condition for 60 year old racing parts, there is some water damage to the layshaft and layshaft 2nd & 3rd gears – see photos. I think metal spraying can recover the mainshaft and the 2 pinions are quite useable in my opinion. Included are the unique 5 speed gear operator, inner ratchet and 5 speed stirrup selector (all unobtainium) plus other gearchange parts
Pinion teeth numbers are as follows (paired numbers always add up to 48):
Main 5th – 28, 4th & 3rd (paired) – 26 & 24, 2nd – 22, 1st – 21
Lay 5th – 20, 4th – 22, 3rd – 24, 2nd – 26, 1st – 27
