Two Totenkopfs. Baffled???

[MarkB]

Hello all!
I came across these not long ago and after reading numerous threads/posts on here i am not really any the wiser as to if they are genuine? and if they are, what regiment or battalion do they originate from?
The larger one i have no idea. The clips on the back look a little to 'modern' for my liking. I got it from a lady whose grandfather did serve in the war and did bring some 'artefacts' back with him. She found it in an old box of his. It's around 3 cms across.
The smaller one is a very much lighter metal. Zinc maybe? and the nearest match i can find is an SS Panzer totenkopf.
Neither have any makers mark or any marks whatsoever.
All opinions would be much appreciated.
Thanks in advance.
Mark.

Hi Mark
The bigger one is fake .
The patin its not orginal and prongs are incorrect and this is alloy
The smaller silver one its orginal panzer skull (this is not Zinc- this is Alu)
No doubt

Hello Peter.
Thanks very much for that. I did have doubts about the larger one but i'm pleased that the smaller one is a genuine item. A piece of history.
Thanks again! All the best.
Mark.
