Hi
I have an early fd with cable stop it's in pretty good condition but it has been used and is missing a stop bolt.
I was gonna keep it cos it was cool but i have decided to sell.
It doesn't have a circlip so if it can actually be used is debatable, but with some simple but careful engineering it could.
The middle A is campagnolo is very feint but this was most likely manufacturing flaw.
And the hole for the missing bolt has been elongated so a bolt can go in but it is quite loose and would need rethreading
