Enlarger Lens Leitz Canada Elmar 1:3.5/65mm

Description

Leitz Canada Elmar 1:3.5/65mm Enlarger Lens.
Estate sale find. Lens was a part of working equipment (slide duplicator).
I have very little knowledge about the item. Comparing to similar items online, this one has a protection filter (lens ?), placed upfront, as a part of the body. For some reason there is a discrepancy between the front plate data of the focus length and the aperture number and engraving on the lens body's focusing ring (65 1:3.5  vs.  90 1:4). The aperture ring feels a little bit loose on the turn. I did not try to clean lens' front and back, they show some sign of wear. Selling this item as is, for parts or repair.
