Hi Michael

I agree with John. Cannot find any reference to Langer, and being a Hauptmann would suggest he would have been a Staffelkapitän or more. Don't believe too much from your Toliver/Constable book, like John said "primary source", without evidence your build false pictures. Judging by the Toliver/Constable Hartmann book they are wildly out on everything. My friend John Foreman always says "Once something is published, it's cast in stone".......basically believed and duplicated/copied.......even when incorrect.

Kind Regards

Johannes
