Hello peoples!
Really wonder how many famous reseachers are here.
I would like to clear one point re DB601A-1 und DB601Aa performance.
Does the DB601Aa really exist or its data only desinformation for future enimies.
Even many primary sources bacame available now, still serious mentions about two types of DB601A (see Kurfurst comments, but anyway great thanks him for materials):
601A-1 1,3 ata 990 (0)
601Aa 1,35 ata 1045 (0)
This usual look for DB601A began perhabs from W.Green and within 45 years still exist.
It seems Aa is only export marking of usual A-1 and appeared in Swiss and Soviet manuals. What abt another customers ?
Story may be common for Jumo 210Da.
Also this point ageed to 109E V max measured in Germany, UK, Fr, USSR, no one overspeed result.
Mr. Mike Williams in his site mentioned Olivier Lefebre' opinion: Aa = A-1 and
maybe this is final point ?
