Peter asked me where I got the figure of 17 for the number of 11 Normale Cabriolets which were converted to 15/6 specification by taking the front from a 15/6 saloon and fitting it to the Cabriolet body.
I believe I got it from this website which is trying to list all the “Traction Coupés, Cabriolets, et Carrosseries Spéciales ”
– worth a look…
