2 Different riveted pads info request

[42rocker]

I'm posting pics of the backs of 2 different lafette pads. Both pads should be early, pre spot welding.
Of course the pad without the strong backing has folded. In reviewing the front etc. I believe that they are from war time and German.

Thoughts???

update
Doing a review of a lafette restore project I found another 2 on each side rivet pad. It was on a
""652 is the code for Metallindustrie Schonebeck AG, Schonebeck/Elbe, Friedrichstrasse 27, Sachsen-Anhalt""
From the pic date was 1941.

Any other thoughts or ideas??
