If hes sold his you can probably work with one of the members here who are located in Japan and see if theyll help you out.

Oh and about my Zeus fork. Uhm Zeus is a old school company. They existed i think 70s-80s they were part of the Campy clones.

Pretty hard to find desired items. They alwasy get snatched up. Im still on the hunt for pista cranks and a track BB but with French threads.
