It is well known that the alloy used to make German aircraft parts from World War II can be identified by the markings on the heads of the aircraft rivets. Duralumin rivets were marked with a center punch or a center punch and a ring. Hydronalium rivets have a ring, while aluminum rivets have no stamping (see photo 1).
But when did people start marking rivets in this way?
This question came to mind when I found an aluminum suitcase that had been manufactured by the Junkers company in Dessau. It has been proven to have belonged to the co-pilot of the Junkers G 38 (D-2500), a famous aircraft that was completed in 1932 and destroyed by the RAF in Athens in 1941.
Until now, it was only known that Junkers briefly produced a few suitcase models after World War I in order to keep its metalworkers employed. However, once Germany was allowed to manufacture aircraft again, suitcase production was immediately discontinued in 1922. And so far, there seems to be no evidence of any later suitcase production at Junkers.
Due to the inscription "D-2500," the suitcase can probably be dated to the same period as the aircraft's construction. It was therefore likely manufactured before 1932. In any case, the rivets on this suitcase are clearly marked with material stamps and, in my opinion, should not have been used before 1922.
I would appreciate any information regarding the introduction of these stamps on rivets in Germany.
