Kriegsverdienstkreuz 1.Klasse mit Schwertern - opinions on the maker?

[callum]

Hello,
If I may call upon others for some quick opinions on the maker of these 2?
To me at first seem like Deumer made - unmarked with the rare stencilled case. I assume this by the outer borders of the cross - seems to correlate with the late pattern zinc Deumers marked 3. The pin also has the length and somewhat shape as well.

Regards,
Callum
