i've seen the same lugs (w/ the 'beef') on remintons (another kierin builder), so i don't think they're proprietary.

110mm rear spacing is pretty common for keirin bikes in general (although they're mostly 120mm these days).

one thing you could look for is the 3rensho "super ends", the socketed trackends and fork ends shown on the bike in the auction.

i believe listmember sasha eysymontt has been doing some work on establishing a 3rensho database/timeline, so you might ask him.

finally, pictures of the bike, especially the bb shell and seat cluster, would help a lot.
