Hello Chris,
I had tried earlier this site:
http://www.wiki.luftwaffedata.co.uk/...._Gr._123_1942
But got no joy...Strangely Dupérier do report that the crew should have been very important, since the Luftwaffe sent a number of fighters and boats to search for the crew on his "War Diaries" (La Vieille Équipe), pg.132, from which I do quote on the original French Language: "L'appareil devait compter dasn son équipage quelque haute personalité de la Luftwaffe, car les Allemands envoyèrent sur les lieux bon nombre de chasseurs, ainsi que plusieurs vedettes de sauvetage; mais tout cela en vain."
Thanks for sharing the machine and crew. Very interesting.
