I am currently in the process of adding a Roland DII / IIa to my collection and whilst investigating the possibility that
Otto Creutzmann may have flown the type whilst with Kest 4 belatedly thanks to a correspondence with Knusel I became aware of an anomaly with the information on him in 'Above the Lines'.
His second victory is listed as with Kest 4b on 24/03/18 a DH4 at Anslingen achieved during an allied raid on Mannheim, but the same publication and 'Jasta Pilots' list his move to Jasta 43 as 20/02/18.
Can any of the experts solve this anomaly for me?
