Hi! I visited a local scrap metal merchant today and found this intresting item. It seems to belong to a German aircraft, because it has some words in german language on it ("Sieb nach 100 flugstunden wechseln"). It also has date stamp: 12. mai 194.. Can someone identify, what part of the plane this is and what plane did it belong? One end has a window in it.
