the manual shows, when they first have written about the automatic, but not, when it was transfered to the fighter units

So I guess the million dollar question would be why a new manual was issued in December 1939 instructing pilots in the proper operating of aircraft equipped with automatic propellor pitch control..

the first manual of a 190 was dated in 1939 Do you know when the 190 entered the war ?

Seriously, I think it just boils down to this: the said 1939 manual clearly shows the automatic system was around by that time, and yes, it did not appear all the sudden, Jagdgruppen didn't just swap their old planes or sent them back to the factory. However I think given that during the 7-8 that has passed until the auto prop pitch was probably fitted to hundreds of 109s by that time, so it was IMHO fairly common.
