Frichs A.S. diesel engine
OK, I was confused because the engine type 6165CV is a 12 cylinder V-engine, but the 8200CV for class MT (not 8220CV as you wrote) is an 8-cylinder V-engine.
Only 2 engine serial numbers (341 and 342) are mentioned for the 12-cylinder V-engines for La Meuse.
MP had 6175CA engines.
