Well, my $46 lens arrived today!
It does work, although totally manual. There is not even metering with this one. No contacts, no screw focus. Totally old school.
Tons of dust when eyeballing through the lens, as would be expected, due to it's age and push-pull design. From what I have seen in a few test shots, it does not seem to appear in the photos.
It does not seem to be a practical lens. Best for a collector, I would think.
It is VERY heavy, and if you hold the camera/lens by the lens, there is a chance of changing the focus, easily. There is no tripod mount to hold onto.
Here is a link to a Matthew Durr review from 2012:

According to Mr. Dunn, this is not a lens to be discounted! I will let you know how it works out.
