By the way, great find Karl.
I recall a few vintage German cars used them at one time. I guess there has been enough resurgence in such vehicles to warrant manufacturing them again. But I'm surprised they did.
EDIT: I just saw on that site it states, "Old stock so they don't shine as beautifully anymore." So they are not being manufactured new again. That means there will be a limited quantity available. I'm sure someone will snatch them up and offer them to us a three times the price.
EDIT-2: I also see a few other really good items in his listings. Might be worth searching through everything before ordering.
EDIT -3: After adding items to the "cart", then filling out the customer information, I see there is no provision to ship to the USA. Did the Facebook page offer a shipping option for the US?
