Nice old bike Steven. The Siam hubs are incredibly smooth. I have a set of hi flange Siam track hubs for a 40s project. Coppi also rode small flange Siam road hubs until the early 50s. If you look at old fotos you can ID the 40s and 50s small flange Siam hubs by the black oil caps--similar to later Campy hubs. Scott Davis Twin Cities, MN USA http://www.sdbicyclegarage.com
