Marc:
      Perhaps you are right regarding some models,
however the Biometar 2.8/80 used for the Pentacon six
TL, Carl Zeiss Jena, is almost identical regarding the
Xenotar 2.8/80, like the 2.8B Biometar 2.8/80 used for
the Rolleiflex 2.8B is almost identical regarding the
Xenotar. Here is an URL with the Biometar 2.8/80 for
the Pentacon six TL and its diagram, similar to the
Xenotar clearly:

All the best
