I've thought about doing this to a Minolta Autocrd- put a Planar from a Rolleiflex in it. But the 3.5 Planars in Rolleis are 75mm focal length, not 80.
The only way to confirm things would be to track down Zeiss serial numbers, and also remove both lens groups to see if there is a serial number on the back group, typical for Zeiss, I believe.
It is possible to move lenses around. The '00' size of Compur shutter block is the same as the Copal shutters in many cases. Here's a Minolta with a Compur shutter and 1938 Tessar-
Actually a very nice lens, and the Autocord is a nice body design. A little sloppy but I bet if I had a working Autocord shutter I could have simply pus the lens in place and replaced the cover.
Oneo ther thing to check is the outside diameter of Tessar lenses. The Roleiflex 3.5 Planar (which is 75mm, not 80) takes a Bay II filter size, but I don't know how much this is because of a wider diameter.
By the way, did the emblem look like the one is this photo?

If so, that's the initial Yashica-mat emblem. Almost always paired with the Lumaxar lenses. Actually a nice color combo, and the mustard stripes on the aperture and shutter wheels combined with green leather make for a sharp looking camera.
