List I have a couple of Headset Locking Nuts that look identical to the locking nut that was recently part of a headset sold on eBay
All the locking nuts that I have are stamped "patent campagnolo" and one is packaged with the part number id 681. The problem is some have a chrome finish and some are clearly (no pun) polished aluminum.
Are both these considered "Record Group" components and secondly do both versions have the same part number ???
