Campagnolo branded chromed steel headset spacer

[Rod_Saetan]

Can anyone shed any light on this please? I can't seem to find it in a catalogue, or a headset it might have been part of. Stamped 'Campagnolo Italy Patent' - the patent presumably dates it to pre-CPSC when they switched to using Brev perhaps? Has a tab on the inside so definitely made for this purpose. TIA.

Looks like the one in the 1958 catalogue here - https://www.retrobike.co.uk/archive/1958-campagnolo-catalogue.903/download

Thanks, they don't appear to be branded though (hard to tell what it really looked like with Campagnolo I know!) and other sources show a #682 part without the branding:

They had the lockring (w/tab) and a spacer (no tab). I would have to look at my bike to see what it has for markings; I think my gruppo is c.'74. Not uncommon to find Campagnolo stuff out there that was not found in catalogs.
