Boris -- oil on the aperture blades of a TLR is not a big deal... the
viewfinder is a separate lens (without any aperture) and the picture-taking
lens doesn't have to stop down and spring back during exposure. So this oil
will never cause any problems with use of the camera. Note that oil on the
blades may be a sign that oil is places where it should not be, which *is* a
problem should the same oil get onto the shutter blades. In the shutter it
will interfere with the operation of the shutter, but oil on the aperture
blades makes no difference to the shutter operation so long as it stays only
on the aperture blades.
His description of the cleaning method is pretty correct also. I use lighter
fluid (naptha) in cleaning shutter and aperture blades, but the "diethyl..."
that he suggests is probably the equivalent.
My suggestion would be that you tell the seller that you believe the
sometime in the future another CLA will be necessary, when the oil affects
the shutter. Ask if he'll give you a partial refund to offset the eventual
cost of this CLA -- how much is up to you.
For CLA of Yashica TLR cameras the 'John Hermanson' of the Yashica TLR is
Mark Hama, I think he has a web site a Google search will point you to him.
I don't know the cost for a CLA on Yashica TLR's, that would be something to
decide how much of a refund to ask for.
