Totenkopf in zinc by Zimmermann, opinions please?

[rbminis]

Thanks Friedrich, Just my last question, I have read that the zinc version for Zimmermann is more rare than the cupal one, is that right in your opinión?, or is just another myth?, also, do you reckon is convenient to give a vaseline bath to this zinc skull for the zinc pest?, these are actually two questions

I believe it is the aluminum version that is more rare.

Thanks Ralph, great to know and out of your knowledge, which one is more rare the cupal or zinc?, if I had to give my opinión, I would say that the Zimmermann in cupal is the most common one

I believe it is the aluminum version that is more rare.
