searched all over for quite a while, finally decided to search 'within'.
looking for a functioning, aka fair-to-good condition vintage threaded headsets with low stack-height <33mm ish. one headset or source-able partial.
(i've
returned a Tange Passage, didn't like the overall finishing quality, wasn't like the earlier ones)
the list of the ones i'm looking for is here. no specific order.
BSA or ITA* threaded + 26.4 crown race, pls.
Dura Ace HP 7500 or 7600: literally an unobtanium but shooting anyway. both models were for Track/Pista hence some of them are with NJS stamps. 7500 has a couple mm lower SH.
Campagnolo Pista* or Gran Sports: pretty much same looking, in terms of shape. both have non-scripted round cups. (vs most of Campy HS w 'Brev Campagnolo Italy' script on the outside curve on the cups).
(1. we do see these on the 'bay but mostly located in Eastern Euro. don't want to wait another 2 months. *2. i realize Tange Passage is a poor copy of Campy Pista)
Shimano 600 (Ultegra 6400): only the one for 600 Tricolor group, also with rounded cups, Not the EX or Arabesque or Arrow. last choice, as not a fan of anodized mat finish.
i understand that any of 'em are hard to come by, would be generous to the aesthetic condition as long as with no grinding/pitts where matters.
willing to mix-match if partially—upper only or lower only—available. holler, pls.
