Up for auction is an excellent condition Made in Germany Carl Zeiss Tele-Tessar 135mm f4 lens.  This lens is very very sharp wide open at f4 but the aperture is stuck wide open.  You probably don't need to stop down because it's razor sharp at max aperture.  That is the only issue otherwise it's a nice compact and crazy sharp lens.  Comes with caps only.  Please email or message me you have questions or concerns.  Thanks for looking!
