The Robin Williams provenance, if it could be backed up, will add value to the bike, but If it wasn't originally built for the Russian Olympic team, then what's the whole point on putting the CCCP and Cyrillic fonts on the bike?
It is almost like they were intending to have owners fool other people that it was built for the Russian team...... which is a bit tacky, IMO.
Saying that, I don't think the Cyrillic graphics and the "CCCP" on the top tube really adds that much more value to the bike. Heck, some nice chrome and unique pantographing on it would have actually made it more interesting.
