Re: [Leica] Used Lenses: wear or very small amount of oil in shutter blades?

["Mike Durling" <durling@widomaker.com>]

I had the blades of a 135/4.5 Hektor buckle and scratch the insides of the
lens because of the oil on the diaphragm.  Since the oil dried out it
doesn't do it anymore.  I'm not sure how much oil is too much.  You might be
safe or you might be sorry.
