ColonelJLloyd is graciously going to sell me some Mafac Racers for a great price, and RHM likewise for a GB stem. You guys rule. I believe I have located an English threaded Nuovo Record BB as well, so basically as soon as I have it all in hand, I'll be good to go! I just need to actually build up the wheels. I'll be using the "Nuovo Tipo" hubs and 27" Fiamme yellow rims from the Atala for now. If something nicer comes along eventually I'll switch them back to the Atala. No word yet from the seller about the serial number.
