These were also available with 36 holes. I have a pair of blue anodized rims.

Hey what do you think, can I use this with a Shimano FC-1056, 105SC crankset?

There is a version between this one and the "fully polished one". I will add a photo later on.

Dia-Compe RGC-400, Royal Gran CompeAngry_Monkey12/03/2014 06:17 PM
I am the original owner of a set of RGC 400s in white. I am adding pictures taken during a maintenance cycle on the caliper and levers. Complete break down of calipers. I'm 95% sure those are the original brake pads. I don't recall replacing them, and they are labeled Dia-Compe:

Calipers, in order from lower left to upper right, QRs and adjusting screws above.  Brake pads in lower right.

RGC 400 levers.  Body, lever, pivot bolt, bolt retaining grub, lever return spring and screw (left to right).  Mounting loop and screw, and nylon bushings (between body and lever) above:

Lever base, Return spring and screw, mounting allen bolt, and the top of the cable mounting hole.  The cable mounts with a special threaded ferrel that threads in from the underside of the base unit.  This is difficult to see when assembled, especially the mounting bolt.:

Campagnolo C-Record Retro-Friction (2nd Gen.)Angry_Monkey11/28/2014 12:53 PM
Additional: The internals rely on a set of spring washers - slightly conical washers. These must be installed "flying saucer" style (back to back, the two larger diameter edges touching). The other components are (from inner to outer assembly): 1. Base plate (with stop tab) 2. Brass bushing washer 3. SHIFT LEVER BODY 4. Small bushing washer 5. two prong core (engages with the flats on the braze-on) 6. The two spring washers (see above) 7. Cover plate 8. D-ring tension screw. If properly configured, the up-shift and down-shift tension is roughly equal, counter acting the force of the derailleur springs. This is unlike the standard friction version. Note:Part names are unofficial - but descriptive. This is based on the Campagnolo Technical News release (30 April 1987) and my set of seven speed Dopplers.

Edit:  Additional information.
These are the component of the 7 speed Doppler shifter from my bike (original owner).  All parts arranged from inner to outer.

This is a scan of the Technical notes published by Campagnolo.:
