"Swirl" is another name for odd OOF rendering/bokeh. Bubble bokeh and
other rendering that old timers like us would consider monstrosities
are now quite popular and sought after among some shooters.
There's an entire generation of young shooters using vintage manual
focus lenses and looking for flare, swirl, and other garbage.
Go figure.

Partly because of the Voigtlander thread here I was looking
up some Voigtlander and Leitz lenses. I feel like I have fallen
into the audiophool world. What the hell is "swirl"? Soft Serv
(no e) ice cream? If you think Planar vs: Xenotar is bad you
should see some of this stuff.

Sounds likely. I am thinking of old radio dials which turn
yellow or brown with age. I have read suggestions for bleaching
them but don't know if any of the techniques work.

I read somewhere, Cameraquest I believe, that it is some kind

I wonder what causes the veiwfinders to become cloudy. Is
it possible to open them for inspection? perhaps its the same
kind of haze that forms inside some lenses. That comes off
with ordinary lens or glass cleaner.

Mine is a post-war Super Ikonta C with a T coated
Zeiss-Opton 1:3.5 f=105 mm Tessar. Just like yours the view
finder is quite cloudy. The rangefinder seems O.K.
I have never used it. When I acquired it many years ago, the
front lens element was 'loose' but that may be normal for
front lens focusing cameras. I was afraid the rangefinder
might be off and set the camera away awaiting future
service. That never happened. When I looked at it today the
rangefinder seemed O.K. after all. I am going to load a film
and test it shortly.

At any rate, the only real, frequent flaw found on the
Super Ikonta C is cloudiness of the viewfinder. While my
camera is, otherwise an obviously well cared for example,
it does have the cloudy VF problem. It is still possible to
frame a photo; if were much worse, it would be worthless
for framing
