Hello,
Currently on ebay is what is stated to be a Flieger Nachlass. Possibly. However most of the photos have been seen before. I have posted it here as at least Royal Aircraft Factory F.E.2b 7669 of 100 Squadron was new to me and along with the well known photo of F.E.2b 5206 of 20 Squadron shows a captured machine. No doubt, 7669 has also been seen be board users more familiar with the RFC than myself. Here are the photos:
