Hello,
Just browsing and came across a photo Album captioned as Flieger Abteilung 46b. As I had not previously seen the photos of Albatros C.I 20/15 (FFA 3b), I hope that means that it has not previously been posted here and is of interest despite not being a recent item on ebay.It can be found here
