If it's any help at this time they are likely from wnr: 210xxx series (Cottbus) and 400xxx series (Fieseler Kassel) Blocks. Could also be some 500-600xxx series in the very last months. Maybe look into aircrafts flown by Oberleutnant Peter Crump of 10./JG54 and 13./JG26 . (13./JG26 was the former 10./JG54). I could find wnr. 210079 "Black 12" 10./JG54 (lost to "Birdstrike") and wnr. 210051 "Black 10" 10.JG54.... but it's a well known difficult task for that period specially for info's on Dora's and very few accounts of 13./JG26 .... Not sure but found a possible wnr. 210121 and also 210080 from Stab IV/JG54 that could have been flowen by pilots of 10./JG54 which was likely in 1945.
