Hi Dénes,

Yes, that red painted "M" is interesting. Unfortunately, I have not found an explanation in the Instand or Reparatur-Anleitung documents. 00400342 would seem to be built in early October 1943, so it could have been built to the standard for full power rating. Also, it might possibly also have had repair or overhaul. But these are just thoughts, I do not have any more info.
BTW, how do you know it was not a later modified Methanol engine please?
Best Wishes,

SM
