Krim shield - Oxidation - Maker?

[stark44]

Picked up this shield from off the E-Stand and was wondering two things..

1. Can someone clue me in on the maker?

2. Should I be worried about the oxidation circled in the photos?
I found a thread a while back showing what it can lead to, and a link to prevent it.. but I cannot seem to track it down.

Thank you.

Deumer Shield, possibly? ?

Thanks!

Thanks to forum member Stöckel for the information!

It is zinc corrosion on my Deumer, which led me to this thread on how to clean it.
