No, never.
Based on the "Made in Germany" writing, I guess it was made in the years immediately following WW2, when the split between the two Germanies was not set up yet. But the question is: was the Pentacon 6 camera and mount already existing then? I don't think so.

So maybe can this be an Exakta mount instead of a Pentacon 6 mount, and the seller did not recognize it?

Or else, I have no idea.
There is also the possiblity of a fake, but it seems unlikely, as this is a shape that I have never seen in any other CZJ lenses.

The only 4.5/300mm lens that Kadlubek lists was made by Meyer as a Telemegor.
But then, Kadlubek is not a complete list!

According to Hartmut Thiele, there has been an experimental model:
1948 - Tessar f4.5 30cm - 4 lenses / 3 groups

Initially I thought it was a remounted Triotar as the mount certainly looks like P6 in that the locating pin is in the correct position.

But then I'm not sure about what focal lengths the Triotar was made in or if any could be adapted for medium format.

In any case, AFAIK the P6 mount didn't appear until 1956 with the Praktisix.

Given the very thin credibility of the seller, I would not risk big money on this lens unless you are an obsessed collector, in which case any craziness is justified Wink
