Hello,
Currently on ebay is a copy of a photo of an Albatros B.1117 at:
https://www.ebay.de/itm/124877130461...8AAOSw7zZhLNNW
Although a copy this is an interesting photo for those interested in German WW.I aircraft serials (just me then!) as there is no reference to an Albatros B.1117 in any of the usual sources. Jack Herris has B.1117/14 listed as a LVG machine in the Aeronaut LVG Vol.1,so there is some possibility that the aircraft shown is B.1117/15. As the nearest batch is usually given as beginning with B.1121/15 a possibility exists that the batch of Albatros B.II concerned begins no later than B.1117/15 and may reach as far back as B.1100/15.
Regards,
Clint
