Trophy artillery on Maginot Line?

I met the information about:
12x 10 cm ex-German guns for the former forts Thionville with gunners and 4x 10 cm without gunners
15x 10 cm ex-German guns for the former forts of Strasbourg and Mutzig
74 guns from ex-germans forts of Metz (10 cm, 15 cm)
Whether there is an information on uses of the French army of German guns. What types of guns were used? In what number? Whether there Are data on the general number of trophy German guns available in France in 1940

Best regards
Cyril

About this kind of question , i remember David Lehmann ( you will find him on "france 1940" ) made something about "trophy" engines and materials .
Maybe he had a complete list of guns ( i don't remember if his text is only about tanks and vehicules or every equipement ) .
Regards

Thanks. I shall set to it this question
