Hello,
Currently for sale on ebay at :
https://www.ebay.de/itm/Nachlass-Fel...oAAOSwl-Fd16wU
are items from the legacy of Ltn Hohndorf of FFA 12. This includes some nice photos. I'm assuming that this doesn't include only aircraft from that unit as the Crahed Aviatik C.I 3538/15 for example is from FEA 10.
Regards,
Clint
