Greetings friends.

I come to you kindly asking for advice.

Could someone please point me in the right direction for reading up on the history of the Armored W126 (Sonderschutz).

I'm mainly trying to figure out how many were built.

And then, as a follow up, I was wondering if someone could point me in the direction of restoration of such grand vehicles.

Thank you and i'll take my answer off the air.
