Thanks Johannes
Very nice of you to make this commitment!
However I am not 100% sure I follow you, and don't want something to become wrong again. If we concentrate on the two crucial days, 23rd and 24th Feb 1943, we have the following
previous scenario (I quote both you and Prien)
Mathews/Foreman
23.2 Uffz Brünke Il-2 07.50H
23.2 Uffz Brünke Pe-2 10.25H
23.2 Fw Bracke Il-2 10.15H
23.2 Fw Bracke Il-2 10.20H
24.2 Uffz Brünke Il-2 06.35H
24.2 Uffz Brünke Il-2 06.37H
Prien
23.2 Uffz Brünke Il-2 07.50H
23.2 Uffz Brünke Pe-2 10.25H
23.2 Fw Bracke Il-2 10.15H
23.2 Fw Bracke Il-2 10.20H
24.2 Fw Bracke Il-2 06.35H
24.2 Fw Bracke Il-2 06.37H
Am I correct that you now also want to change one of the victories on the 23rd to Fw Bracke? This may not be your intentions and I am simply not understanding you well enough.

But for the sake of completeness, I then assume you want to change the Pe-2 from Brünke to Bracke? If yes we would then have a final scenario as follows
23.2 Uffz Brünke Il-2 07.50H
23.2 Fw Bracke Pe-2 10.25H
23.2 Fw Bracke Il-2 10.15H
23.2 Fw Bracke Il-2 10.20H
24.2 Fw Bracke Il-2 06.35H
24.2 Fw Bracke Il-2 06.37H
Is that correct or not?
With regard to the score on 12.3 both you and Prien have the same man
Fw Helmut Brünke. However there then is a problem with rank. I know you now say the score on the 12th was by UFFZ Brünke, so can you confirm the list/document really states that rank and not Fw, since then I would say there is a slight problem remaining....
I also find it interesting with how the umlaut was written. To me it is an indication the typewriter used was not of German origin....
