Ross Zeiss Anastigmat 170mm f/6.3 Brass Lens GOOD

Ross Zeiss Anastigmat 170mm f/6.3 Brass Lens. Ross Zeiss Anastigmat 170mm f/6.3 Brass Lens Very rare lens created in collaboration between Ross of London and Zeiss. The lens is in good condition for it’s age. There is a bit of element separation around the outer edge of the rear lens grouping (see photo). I think it would be out of the image circle. The f/stop is interesting as it features click-stops; rare feature on a lens this old.
Lens does not have a jamb-ring.
