as seen in the showroom of the Alex Singer store in Paris. I inquired about it and was informed it is a late 1940s Singer that had been retrofitted at some time in it's history. Yes, it does have delrin Simplex stem shifters with Huret Allvit derailleurs. The Stronglight crankset appears to be original, as does the riveted large flange Maxicar hubs. I really love the rake on the fork. it was not for sale.
