This is a 135mm f4 Super-Multi-Coated Macro-Takumar for Pentax 6x7 cameras.  Included are front and rear caps.

Very good cosmetics with no dents or dings.  There are many small marks in the finish.  I think the owner liked this lens. See pictures!

The focusing needs to be relubricated - the grease has dumped is oil on the diaphragm blades.

The aperture ring is smooth but there is oil on the blades.  See last picture!  The automatic mechanism works slow and the lens should be serviced before use.

Glass - all glass and coatings are beautiful with no cleaning marks or haze.  There is only a small amount of scattered internal dust from age, which will be removed during the lens service. 

Nice project!
