Very clean used Hella K1447 Adenauer right Taillight Lens for the 300B+C.
The chrome is beautiful and ready to go on any car, even show quality, but the Red lens has an internal stress crack. It does not come through. You can easily replace that lens. I previously sold NOS lenses for $400 so this one is priced accordingly.
I can take a red lens from another taillight and transfer it but the cost will be more. Ask for details.

I also have others in lesser condition if you want to save more. See the other listing.
