Hi Christian,

the code implies that it was registered in Germany and therefore could belong to:-

Lufthansa (or one of its related airlines such as the German-Russian Deruluft)

or was in paramilitary use (i.e. the clandestine Luftwaffe)

or another government/research department

or was in actual Luftwaffe service (on loan, impressed).

Cheers
