In the memoirs of "Colonel Henri" of the Abwehr he claims to have arranged and captured many weapon drops as a result of Abwehr and SD penetration of the Resistance and SOE. What the Germans did with such arms is anyone's guess, though I believe they armed the Vichy Milice militia with some of them.
Probably most ended up in the hands of the central government at the end of the war, unless some local governments or officials held onto some for the political reasons 30Three mentions.
I wonder if the Milice put any markings on theirs?
It would be interesting to know what the breakdown of dates and manufacturers was - No4(T)s were sent, but were any included? Probably prized souvenirs those and not likely to be turned in.
