My backstory: got a nice Italian-built late '80s frame with no fork. I bought it knowing that I HAD a couple (1" threaded steerer) forks that MIGHT fit. Well, turns out one is too short and the other too long plus the too long has a limited amount of threading.
After I fit a Stronglight A-9 to the "too long fork" I discovered that it wasn't just a problem that spacers would solve (due to the limited threading) I considered that IF I could find a local shop who would cut about 12mm more threads I'd be golden, but been there/NOT done that with a previous fork and there was NOBODY in the SF bay Area back then who would cut new threads in a steel fork steerer...I had to ship it to FBinNY who did a fantastic job (but I don't want to keep imposing on him).

SO, my thought is I have 2 possible TALL stack headsets which MIGHT work without anything more than spacers (or some trimming of the top end of steerer) but both of these need a crown race.
One is a Campy Super Record 4041 which has a stack of 42.2
Two is a Campy Veloce which has a stack of even greater than 42.2

BOTH are missing their crown races so my call is for anybody who has 26.4 crownraces for either of these---sell me or trade me, PLEASE.
OR anybody who has swapped another brand or model of crownrace for either of these HS---tell me what fits, for example: does a Nuovo Record race fit the Super Record HS, or...?

Last option: anybody have a complete TALL STACK (approx 43mm+) HS with 26.4 race and ISO/Brit/Ital threading in good nick they want to sell or swap? I have a decent Stronglight A-9 I'd trade...and lots more.

All help appreciated, THANKS!
