Dia Compe DC-750 are in production and available new (with allen bolts for the brake arm connection for a more modern appearance), and you can interchange some parts with DC-610s to install them with recessed nuts on the rear - the stock units can be installed recessed on the front.
I have Dia Compe DC-610 front and DC-750 rear on my Riv Mystery Bike - similar to the Weinmann 610 front / 750 rear on one of my Paramount P-15s. You can also get GC-700 centerpulls that use post mounted brake shoes similar to Mafac / Rene Herse.
