About Quiz #372: 1928/29 (Vernon) Derby 6cv/9hp Coupe


1929 derby_9hp_coupe_michael_costigan_470

Lots of highly detailed answers came in on Quiz # 372  causing a slight headache with quiz-sender Michael Costigan  and your editor.  One can take two directions looking at the picture. France or England. The car is either a Derby as marketed in France or a Vernon-Derby as sold in the UK. So we would accept both answers as correct. As the picture is from a Vernon-Balls brochure we cannot really pinpoint the exact year, but it could be 1928 or 29 as after that the design of the wheels showing theirbeautiful XL brakedrums was changed to a more conventional hubcap look.

Where many went wrong is with the engine to be expected under the bonnet. For sure no six cylinder Cime, as the six cylinders had a longer chassis and bonnet and a flat radiator (similar differences were seen with Amilcar). The basic engine - at least with the french cars - was a Chapuis Dornier, more sporty Scap or Ruby engines were also available. From the Vernon-Derby catalogue Michael Costigan concludes that the UK cars came as a standard with the Ruby engine. Finally the model/coachwork. With Derby it is described as Cabriolet 3 passager Grand Luxe. With Vernon Derby as Sportsman Coupe.

So the fully correct description is either : 1929 Derby Cabriolet Surbaissée Grand Luxe (with 6cv Chapuis Dornier, or Scap, or Ruby) or 1929 Vernon Derby Sportsman Coupe (with 9HP Ruby engine). Of all Derby/Vernon Derby senders Jorge, Mike Tebbett, Calum Walsh, Poisson were quite good, however in the end we decided Kieran White is best. Congratulations Kieran. We like to thank Mike Costigan for helping sorting out the correct answers. He decided "I think I'll stick to trying to answer quizzes in the future, it's much easier!" Well Mike, next week a new chance.
