2¾HPGearbox Sprocket 2 speed
« on: 12 Dec 2006 at 06:38 »
Hi everyone,
Does anybody have a spare G/Box sprocket ½inch chain pitch for sale, or swap for a sprocket with 5/8 pitch .
Round about 1919 1920 Douglas changed primary drive chain pitch from 1/2in to 5/8 i appear to have the later g/box sprocket ,as i am building up an early model would like to stick to the earlier specs.
So please if you can help i am nearly there and another takes to the road.
