i have sat before me two very nice brampton headsets. a nos 'continental' and a lightly used, but prettier and originally higher quality, alatet. they're different sizes!

british standard PAH!

two sizes of british headsets! i only found this out recently when a headset i was interested in was advertised on ebay as having a 30mm 'spigot'. the spigot turned out to be the parts of the bottom and top head races that fit into the head tube. as you all know british standard is 30.2mm. so what's up with this oddball size? it was explained to me by the vendor - peter paine, that the sizes could be told apart by the presence of a groove around said spigots on the 30.2mm size.

trouble is both my headsets have grooves but the alatet which i wanted to use falls out of the frame- headset press not required.

were these 30mm headsets common? would it be possible to have the ID of the head tube shimmed or built up with brass? -the frame is being repainted anyway.

does, by some miracle, one of you have a 30.2mm brampton alatet headset they would like to sell me, or even better trade for my odd 30mm one?
