Those appear to be it. The composite was later used as grips for pistols. . The dust caps have a little hex key set screw that comes out, and you can actually force lube in that way if you want. The caps are press-fit in, so a thin wedge (I used a set of automotive points gappers) can pry it out, and you can clean and repack the bearings, then put it back on.

The first set I had came with black spindles, black cages, by Christophe. My second set, from eBay France, had chro-mo spindles and chrome Christophe cages. I still have them, never thought much about them until this thread came up. I also have a spare dust cap.

They are no beauty queen pedal like the 600 tricolor cage pedal, or others, but they're light, spin smoothly, are rebuildable, and I like the cage. If I could figure out a way to make some Christophe mini-clips work, I'd use them on my commuter.
