Is it a threaded cog?

I think that this is the place.

Thanks.

I will send an email

fingers crossed it all worked out & for once my memory load of seemingly useless retro knowlodge might actually come in useful

Sorry Scant, but Andrew from Yellow Jersey has just replied to me with no success (unlike Sachs )

At this time I have to go ahead.

Holly grail was also a long term search.

And on this path, your retro knowledge has opened Yellow Jersey doors for me.

Holly quest...

By the way, I have to inquire in Sachs/Huret/Maillard jungle.

This will be a little bit hard.
