Hi,

I am in North Lincs.  but will be putting it back on the bike soon.    The only difference is the two notches for turning it and the off centre hole so probably not too difficult using a concentric one as a a starting point.
I think I may have another cup somewhere but I am not sure if it is an eccentric one.  I will have look tomorrow and let you know.

Dave.

Hi,

Unfortunately I do not have another one. In fact I do not even have another concentric one.  To be honest although the eccentric cup makes getting the gear change spot on easier, my other A65 with a concentric cup is good as well.  I tried the spring both ways up and one way was better than the other.   I think that, as has been mentioned, a washer brazed on off centre by a few mm and the hole opened up would do the job.
I could take a few more photos if you wish.

Thanks for looking Dave I've got a few more irons in the fire on this although to be honest it doesn't look too positive. I would have thought someone would have known were the drawings are or at least if they have been destroyed or not. I've got access to a concentric one so I can get the basic dimensions from that and I will use your photo to estimate the off set and machine something just to try it.

Hi,

I did bit of digging and the conclusion seems to be that as this was a late modification and not long before the factory closed there would have not have been many if any made for the spares supply market.
