Hello shakaali!
First of all, happy birthday!
What I found, it's not because of my knowledge of airplanes ...
I got to see the Finnish national insignia under the wings.
By the AA of your nickname I assumed you were finnish (confirmed with your profile)
So I just looked for a museum of historical aviation ... Suomen ilmailumuseo and there I started looking for the planes I did not know ...
I found this:
Adaridi AD3
It would have been fun if the museum was designed by Alvar Aalto.
