List of known Ar 234 Stammkennzeichen and Werknummern?

[Franek Grabowski]

Trying to rid off old errors might be a futile exercise. They used to bounce back.
As for database, usually there is a critical point, which must be passed through to start to make sense out of it. Out of my experience, there are just few areas, where one hits the wall, for example No 307 Sqn Defiants, where serials were consistently filed in all records sans individual code.
Of course, it is much harder with Luftwaffe, but I bet there are still plenty of documents to be reviewed.
