Westwall Medal Question

[R.R.]

I purchased recently this Westwall, Carl Poellat pack marked with a nice brown collor. But comparing it with another Westwall tombak made I have, I observed it's a little bit light.

I know tombak and zinc made Westwall medals, but seems to me this one is cupal made. My question is, there are cupal made Westwall medals?
