Hello,
Currently on ebay is a photo of the Lohner 10.19 at:
https://www.ebay.it/itm/124860706727...gAAOSwTfJhHi6m
The rear pf the photo appears to indicate its from the Peter M. Grosz collection - which is strange as its not in the KuK aircraft book he caoauthored with Haddow & Schiemer.
Regards,
Clint
