Tele-Xenar's and Angulon's

For a 6x9 system I acquired a 180/5.5 Tele-Xenar and a 65/6.8 Angulon.
The Tele-Xenar is Linhof branded.

If we assume I am lucky to have some good samples what are the max.
performance these lenses can deliver?

When I do some google search most go for the Tele-Arton, Apo-Symmar's,
Super-Angulon's etc.
What apertures are best to use to get best corner sharpness? 22?

Any sources where I can see to test images where these lenses has been used?

Another issue:
Is it true that you can take an old Componon S enlarger lens (e.g. a
100/5.6) and unscrew the front and rear element group and
then mount it in a Compur shutter (should just fit I heard), and then use
this lens as a taking lens which also performs well also at infinity?
