Another acronym
– I have enough problems working out what an engine is without MOWOG, SVW et al.
I assume therefore that the answer might, and I only posture migh, be the “SA” class?
The SA was marketed as the "Two Litre". However after the SA was announced at the October 1935 Motor Show, and before the SA was available at the dealer network, the factory increased the engine size to 2.3 litres to give the car better performance in a competitive market. It had Paul’s "Jackall" jacking system with independent jacks at each wheel.
I won’t go on as, sometimes, it is better to keep quiet and be thought a fool rather than put words to print and be proven one!!
