Noctilux - is this fungus?

I purchased this circa-80s 1.0 noctilux online from a dealer.  I am within the return window.  I wanted to ask about this residue on the aperture blades.  Its hard to get in focus, but there are a couple of spots that appear to be white with a little bit of slightly darker bleed around them.  They are definitely on the blades because they move with the blades.  I don't see anything in the glass itself when I look through it.  Should I be worried about this down the road if I hold on to it?

Crlong,   I totally agree with Peter in Post 2 and based on my experience with fungus on M lenses while stationed in Panama years ago.  Send it back ASAP.   r/ Mark

Agree with Steve. Gunk on the iris blades is not destructive glass fungus. A simple CLA will take care of it. Contact the dealer before returning. In my experience a good dealer will take the lens in and return it serviced without extra charge.

Here are better photos.  Also see the marked spot which looks like there is some internal paint loss. Is this normal considering the age?

Looks like it could just be Schneideritis - google it to find out more. The alternative is separation but I doubt that you'd get separation of two different cemented lenses in the same place without an impact mark to indicate why.
