I've been lately researching about the last Bugattis built (Type 73, 101, 251 and 252) and I've stumbled upon some info regarding the 101 C Antem Coupé and the 101 Guilloré Coupé, mentioning the rest of the chassis (eight in total), but the timelines described don't add up with each other. I'll leave you the articles on the auctions of both cars: "Eight cars were produced in total and allocated chassis numbers 101500 to 101506 inclusive, possibly missing out chassis number 101505. The prototype, chassis number 101500, was a factory-built, four-door saloon with coachwork in the modern, full-width, postwar style, whereas chassis number 101502 was a coach (a two-door saloon) by Guilloré of Courbevoie and the only Type 101 to feature separate front and rear wings. According to Barrie Prices 1957 Album Bugatti, the body is believed to have been conceived for a Delahaye. Two further examples, a cabriolet and a coach, both by Gangloff of Colmar, were displayed at the 1951 Paris Motor Show held between 4th and 14th October. The former was chassis number 101501 and the latter (perhaps originally the missing chassis number 101505) was, for some unaccountable reason, allocated the Type 57 chassis number 57454 from one of the 1936 Type 57 G Tank sports-racers. Of the three remaining cars, chassis number 101503 is another, more attractive, Gangloff cabriolet, 101504 is a two-seater fixed-head coupé bodied by Antem of Paris in 1955, and 101506 was fitted in 1965 with a futuristic open two-seater body by Ghia of Turin. All seven cars have survived to the present day, three in the French National Motor Museum at Mulhouse, and all except 101502 are listed in Hugh Conways 1962 Bugatti Register." -----------> in http://www.bugattibuilder.com/wiki/index.php?title=101502 (Bonhams) "Four years passed in which the family partially settled its differences and the Molsheim works were rebuilt, supported by orders from the French railways for parts and service on the Royale-engined Bugatti railcars, subcontract production of weaving looms, castings, and machining work for Citroën. But the Bugatti automobile remained central to the Bugatti tradition and general manager, Pierre Marco, along with Roland Bugatti the youngest of Ettores children from his first marriage created the Type 101, two examples of which graced Bugattis stand at the 1951 Paris Salon. These were a drophead coupe by Gangloff and a two-door coupé by Paris-based Antem the car offered here." ----------> http://www.ultimatecarpage.com/forum/classic-cars/948-bugatti-type-101-ghia-roadster-3.html I mean, the Bonhams release states the two prototypes presented in Paris 1951 were the #101501 Gangloff Cabriolet and the #57454 101 Gangloff Coupé, being the #101504 101 Antem Coupé delivered in 1957. On the other one it contradicts, saying the two presented were the #101501 Gangloff Cabriolet and the #101504 Antem Coupé. COuld someone shine some light to this subject?
