Interesting document Gerben.
Concerning the Mauser documentation available in France, about two years ago I kept in touch with the DGA - Direction General de l'Armement to figure out if these documents are available for analysis.
DGA replied that these documents are not classified so far, therefore there is not an organized archive.
The only information about the Mauser production under French control are mainly based on studies of serious French guns enthusiasts.
In my web site, if you click the link LP08 made under French control, you can find a receipt released by the French authorities to the Major Sutternin.
With this receipt, the Major Sutternin received a P08 for 350 Francs.
The receipt is dated Oberndorf 7th December 1945
