I am in SoCAl, and I bought a matching pair of '76 Superleichts, one was a 23" the other was a 25". I needed a 24", so I kept the one that fit best (23") and sold the other. I paid $700 each, and they were unused, but knocked around a bit. They still had original tubular tires, but they were dry rotted. Both Regina freewheels has been replace by wide range Suntour Winners. On the bike I kept, I rebuilt the wheels with Sun M13II rims, the original Fiames are in the attic if I ever want to restore it. If I had know how coveted they are in Europe, I would have kept both and sold one over there.

Here are some photos of the 25", it still had the Ideal saddle (not the Ti rail one), I would have kept that. I sold this bike to a guy in Washington.
The 23" is still in the bike box I used to ship it back from L'eroica. As soon as it is put back together and cleaned I'll take a few pics.
