Grrrrrrrrr.. randomly I did have the top half of a modern Record but I used it elsewhere!
However, I do have a late '80s/early '90s Campy Headset... not sure if it's Record though - how would I ID it? The crown race and bottom cup are fairly worn (hence it getting replaced) but think the top half would be ok. Would only want postage for it to be honest as it ain't as pretty as you would want.
Possibly consider this a back-up plan / budget option
Somewhere,, amongst the mancave I've got a Record OR top race , where the bearings sit into not the threaded locknut the part below.. that any use.. if it is then I'll dig it out for you and you can have it FOC..
