A very strange little engine.

For one point, specify the year, make, model, and coachbuilder of this car

[sixtee5cuda]

Can an Expert decipher this puzzle?

[AlexFrance]

Is it the original engine of the car?

[gilescooperuk]

From the styling the car appears to be pre-war, does the engine date from the same era?

[sixtee5cuda]

This is the original engine in this car.  Both car and engine were produced before WWII.

1933 Derby V8 with roadster body by Duval. These were the last Derby cars to be produced. The Lepicard designed cars had engines with side inlet valves and exhaust overhead valves driving the front wheels. This roadster has a body called "Montlhéry" and was used by Gwenda Stewart in the 1934 Monte Carlo Rally. Two V8 Derbys ran unsuccessfully at Le Mans in 1934 and a single further entry also retired in 1935.

Point awarded to ropat53 for the complete answer.

I found a picture of this strange green roadster, and I thought it would make a good puzzle, mostly for being offbeat and generic looking.  Then I saw the side/overhead valve engine, and figured the engine would be a better puzzle.
