Hello,
Currently on ebay is a photo of naval Albatros LF.121 at:
https://www.ebay.de/itm/234132724497...4AAOSwGaJhE6Wz
I believe that its an Albatros B.I, based on the three bay wing of the aircraft shown in the link at the end of this block of text,assuming both photos shown the same aircraft.Should this not be the case then the aircraft is a B.II as recorded in Aeronaut's the Development of German Warplanes in WWI P.121
