Well done as usual MJ The patination and accumulated gradual wear points you make are the same concepts one should look at with helmets and firearms as well. Nice Hillary ref. at the end with Gotfried's book. I watched his one episode show on Netflix where he and some Brits were annoying each other and some local backhoe operating Balts digging for Nazi rust. I think they found Josef Mengele's Bolivian EBT card.
