Angel Garcia mentioned the Nuovo Prestige frames, this one sounds interesting to me:
from Alberto Masi's website http://www.milano3v.com/
Pista per Strada -new lugged steel frame for fixed gear riding The "Pista per Strada" or "track for road" is a fixed gear road frame built with the last of the"M" cut out original Masi Prestige bottom bracket shells and one inch top tube and one and one eighth seat and down tubes. Same steel fork as the Nuovo Prestige available threaded or unthreaded or with carbon fork. Seven o'clock mounted brake cable guides and rear brake bridge. No water bottle bosses except by request. Rear dropouts by Tecnociclo are similar to original Campy track dropouts but with decorative cutouts. Frames will be landed in the raw for U.S. painting and decaled "Alberto Masi." Made to measure available. Price is the same as Nuovo Prestige frames. Fixed gear frames for velodrome riding, i.e. true track frames available by request. Call or write for details.
