Rules One, Two and Three.
Had an apprentice on the ramp for the first time a few years ago. I explained ramp safety including the above. He was, "yeh, yeh, yeh, whatever", and promptly walked through the prop arc.
He lasted about a week with us, sent him back to the hangar.

As to the photo, East European? (looking at the hats).

Hannover CLV?

No Mel - but you are close. Think Post-Armistice...

Ah! You've cunningly hidden the middle wing! I thought the fuselage/top wing spacing was small for a MkV
It's the F10

And it's back to you Mel - yes indeed, the Hawa F.10 triplane Limousine.

Not a lot to see - but a very distinctive tail. Thinking you are still in Germany and that top right white area is a deployed emergency sail.
Take it away and it should look like this....

Oh well, I thought that might have lasted like my previous wacky aircraft challenges, the flying submarine and the inflatoplane.
Crazy stuff!

Cheers Mel - must be time to break the cycle and declare Open House.

An appropriate challenge for this thread which has been too quiet

well I'd say it's a helicopter but that seems far too obvious with the Master posing a challenge..........................

Trendak Aviation Taurus gyroplane?

BEAgle is on the right track.

Trendak ZEN-1?

Yes the Trendak Zen-1.
It later evolved into the Taurus but that doesn’t have the stepped bottom line of the window.
Over to you Noyade.

Thanks Bear - but I was just following on from BEagle. Please give control to him. Cheers!

BEagle please take the reins.

That's very kind of you, Noyade and Self loading bear!
