Amar f4.5/105mm
Emitar 4.5/80
Mikar 4.5/55
Enlarging Lens
42mm screw thread (M42)
click stops
Tested. Good working condition. The lens has a large working distance. 
In order to use this lens, you need to add macro rings, I added 60mm for Amar, 11mm for Mikar
I am not sure why an enlarging lens should have a what appears to be a deep built in lens hood: maybe it was also designed to be used with close-up bellows.
CONDITION:
Very good cosmetic condition, see photos
