Make, model and year for a point

It's a 1928 Alma Six. It was built from 1926 to 1929 by the French engineer Vaslin in very small numbers. Very intersting was the engine designed and built by Monsieur Vaslin. The inline six of 1.8 litre displacement featured four valves per cylinder and two carburetors. Normally only one carburetor and two valves per cylinder would be used. But when the car reached 85 km/h, the second carburetor would start assisting by using the other valves.
Perfect answer - thank you.
