I acquired a reverse conversion that might interest readers. Some have called it tragic, it's certainly an interesting example of customization. The bike is a 1960's Cinelli Pista. Per the seller, back in 1968 the owner wanted to make his "dream bike". Took this Cinelli, added a derailleur hanger (crudely) and cantilever studs, then chromed the frame. Did a road build with bar-end shifters, Mafac cantilevers, etc.
I like it and decided long ago not to pursue a restoration even though the chrome is so so and having a track frame with cantilevers is kind of silly. I've dubbed it "Pista-Strada".
Here is a wooljersey shot of the rear derailleur hanger so you can see it's location. There are other pix of the bike as I bought it.
