Does anyone have a link to instructions to get to the aperture of the early, Canada, silver 90mm summicron with the collapsible cup hood? Mine has oil and I'm thinking I might try to work on it myself. Thanks, Bob.
 
That is fairly cheap repair... under $75 with most repair shops...
as long as nothing else is wrong. A True cleaning and re-lube may be tad more, and would include replacing the old lube, and cleaning the Iris, and the exposed elements of the 2 glass blocks.

I tried goggling it, no luck on finding a repair Manual.
