Some more from the old negatives box.
These must have been taken in the early 1950s on Luxembourg airport.
The Klemm LX-MAF is still alive. It even belongs to the 'patrimoine aƩronautique national'. The pilot was known for taking along a trumpet and making music while flying over villages.

That's what LX-MAF looked like in 1981. I've read in Wikipedia that it's for sale apparently. The plane is a Klemm 25.
