What two English vehicles of the late 1930s, each one of the most popular of their type (but very different to each other), used engines with metric threads, despite these engines being built in England by the manufacturer?

Manufactured by Mercedes-Benz used a proprietary motor and what motor was it?
If you don't like trucks, stop buying stuff.

Are you thinking of the 1.5 litre motor in the A class merc??
Neither was a motor cycle, and while both engines have French ancestry, one only obliquely, both engines were designed by and built in England by the company who built the vehicle. (Strictly one was an associated company building the engine, but same English owner) Both vehicle designs were purely English, although one was built in significant numbers (a slightly later model) in several other countries including Australia, as were the engines.

I thought originally the Austin 7 but possibly too early, However British Morris and MG engines from 1923 to 1955 were built using metric threads but with bolt heads and nuts dimensioned for Whitworth spanners and sockets.[6] The background for this was that the engines were produced using machine tools of a previously French-owned company that was set up for metric production; for the average British motorist to be able to service his car, the bolt heads had to fit imperial-sized spanners.
Do I get a prize if I'm correct John![]()
Got one of them. Morris was buying engines from Continental in the USA from 1913 to 1919, but import restrictions meant this was no longer feasible, besides which, Continental stopped making that model. Morris tried to go back to their previous supplier, White and Poppe, but they had just been bought by Dennis.
Meanwhile, in 1914 Hotchkiss had hastily moved a factory from eastern France to Coventry, but the demand for machine guns had dropped abruptly in 1918. Hotchkiss produced an engine for Morris bearing a suspicious similarity to the Continental engine, except, since their machinery was all metric, so were all the threads. By the mid twenties, with Morris virtually their only customer, Morris bought the UK branch of the company.
One down - what was the other one?
