WW2/WWII GERMAN WAFFEN SS CAP / Not suitable for wearing best for display.

Found in an old home being demolished along with some other things I may list. Unsure of authenticity of these items .
On what I could find the visor eagle came back as being made by F Wagner in 1943 and was said to be authentic however other searches say it’s a “ fantasy” piece. Made of zinc and back is marked with the SS bolts , 475/43 and then RZM in a circle. 475 was identified as a factory code for Fernaid Wagner and 43 is supposed to stand for 1943. Has all 3 original prongs attached and they are solid and strong. Some dirt is caked on front with some silver/ white finish showing.
The Skull is actually made of silver . It was dark black but it cleaned up nice. It didn’t look like steel or aluminum so I tested and it tested positive for silver . Between 80% and higher purity. No prongs like on the eagle .
Cap is made out wool? Doe skin? Has tears and small rips. Doesn’t glow under black light. Filthy and selling as is because I just don’t know could be private maker or old repo
