I know its a long shot but have drawn a blank elsewhere hence asking on here.
I have just started back on my C15 rebuild and have just removed the rear mudguard and rear wheel. (By heck that rear wheel weighs a ton!!!).
Some of the teeth on the sprocket have lost their tips so I am looking for a good second-hand replacement - BSA part number 40-6018 - 45T .
I know I can buy new and, ideally, should be buying both front and rear sprockets plus a new chain but I am happy to use second hand as the chain and front sprocket will be a better match for it
If you know anyone with a stash of C15 parts please let me know!
