Super Ikonta A 531 Reaching for the Shutter (13)

            Zeiss Ikon Super Ikonta A 531.
German 4,5x6 rollfilm rangefinder folder from c1937.

So it took me a long time to remove the Middle Lens of the Tessar. Reasons were a long stay abroad and the fact that I had to build a Jig to get that lens element removed.

It was very interesting to see that after some months the fluids that I had used in an attempt to smear the threads had caused some damage (see red arrow). I had used WD40 combined with Lighter Fluid and had injected that into the threads. 
As it took almost 3 months before I was able to remove the middle lens these fluids had managed to do this unholy damage :-( 

You see this damage all around the rear rim of the lens element and (from the front) it looks like the black paint over there has flaked away.  However when I had a closer look at the rear it was clear that the paint had not flaked away but had formed a ring of blisters. Everywhere there is a blister and the paint no longer touches the glass you will see a white spot. Grrrr......

This is of course repairable with some cleaning and a fresh coat of black paint but takes again some extra hours of work.

I have seen these kind of damages before in camera lenses and now also realize what could be the cause.
