Thanks Clint

Sounds pretty much like you are correct.
The officer looks much like a German and the guard could very well be something within the Latvian local police force.

Then of course we could forget any KuK connection and of course the capture is by the Germans.

I don't believe any list of captured flying objects exist from their side, does it?

Can't remember seeing one....
We are soon leaving our hotel and I will not be back home until very late this evening.

Cheers
