@ Peter Achs : nice pics!
The first one is perfect illustration for these peculiar "Sanitäts Ju-52s".
For the last one, the "common" Ju-52 seems to have a Stkz beginning with 1Z+.. May be was it a complement aircraft for the aerial salvage operations?
@ Everybody : thank you very much for replies which give me precisions on the orerational duty past of those planes.
@ Von Alles : where have you seen the "lot of pics of them during late spring & summer 1940 in France " that you evoke?
Best regards,
