Hi guys
I own this lamp
It's clearly german style made but I haven't already see this model exactly anywhere
It's a medley between those ones

(page 49)
and

(pages 2 and 51)
It's almost similar with the 8041 of this reclame
and very similar with the one of the bottom on the top left corner, but can see the reference because of the poor resolution.
I'm so looking for a confirmation of the ww2 era german made, producer and reference model, attribution (military of civilian), producing dates, and maybe a pic in better resolution of the first reclame, the type of battery to make it works; and the top, a period picture showing this model.
For information, it been found in France on May 1940 battles territory.
Thank you very much for your help.
Fred
