A gentleman has contacted me on my site regarding a 1975 Allegro he recently inherited. Red, white graphics and white detail around lugs. I believe they are Prugnant lugs from his description. Decal theme is like mine posted in the gallery of http://www.allegrobikes.com. He says it's 55 c to c. Original paint, decals, components, as follows (some he didn't mention, this is all he mentioned):
3ttt Record stem and bars, Weinmann brakes, Stronglight crankset, Lyotard pedals, Tipo low flange hubs and I believe from his description Arc en Ciel, Campy NR shifters and cable guides, Suntour rear D, two saddles: Brooks pro and a Unicantor. I have not seen the bike, he taking pictures of it now. He lives in Orange County, CA.
He's in the process of taking pictures.
If anyone is interested, feel free to contact me, but please don't copy the entire group here.
