Hi, Charles Bavarois has rather kindly posted the following over on LEMB
here. He gives details from a document he has that again mentions this WNr. and to it to being an E-3:
"Berichtigung der Rechnung Nr. 5018 vom 12. August 1940"
"Wir berechnen die Teillieferung von 33 Stück Flugzeugen Bf109E3 Werknummern 1641-1659, 1980-1993 zum Zellenpreis von je 59.000.--"
He offers a rough translation:
"we charge you for delivering 33 Bf109E3 , serials 1641-1659, 1980-1993, at 59.000 Reichsmark for each airframe ".
I'm unsure if this adds or subtracts anything to any other period documents relating to this WNr. but posted purely for interested parties.
