Ah, perhaps it is for a Pista hub then? Anyone know if Campagnolo pista hubs retained the 18mm locknuts into the 1970s? Good info, thanks...

Hi Mark,
Many thanks for the explanation. The 18mm locknut is indeed stamped with "CAM. 73" (without "P") on the inside face, whereas the 17mm one is stamped "CAMP. 81" but on the outside. Fascinating, isn't it :)
Again, thank you.
