Very curiously two patents were taken out within two hours of each other in two different countries with double rim ferrules. In Italy Mario Longhi registered his patent on January 5th 1934 just two hours before Mavic in France registered their patent for a virtually identical design. Longhi licensed his patent to Fiamme (hence on early Fiamme rims the words Brevetti Longhi) and very graciously also allowed Mavic to license his patent as, of course, his patent had priority over the Mavic one. But more mystery surrounds the introduction of the rims \u2013 the design and actual rims were exhibited in England at the Lightweight Cycle Show in November 1933 two months before the patents were taken out\u2026
