Hello,
Currently on ebay is a photo of LVG B.I B.112/15(?) at:
https://www.ebay.de/itm/Orig-Foto-Fl...kAAOSwtsNfYOZ~
I have some doubt about whether this is a Bestellnummer rather than a flying school assigned number, if it is a Bestellnummer then it is a previously unknown serial. It could perhaps be a previous Bavarian air force number, transferred over to look like a Bestellnummer which did happen. Indeed this machines markings resemble a number of Bavarian LVG B.I (Ot) in Aeronaut's LVG Aircraft of World War One Vol.1.In any event an interesting (to me anyway
) photo.
Regards,
Clint
