Is this the Pentacon 6 or Praktina mount?

Pentacon 6, not Praktina.
I have lenses in both mounts, they're quite different.

Really hard to see, but it looks like a Praktina, praktina is a 3 prong bayonet.. I just got an adapter in from Rare adapters. Unfortunately a week long business trip. Praktina to L39....

Was wondering about Biometars how does it render?

Definitely not Praktina ... the DOF lever at the top right-hand side in the picture and the adjacent lug is Pentacon 6 ... there's no DOF lever on the Praktina lens!

Pentacon 6.

I have the same lens (Biometar 2.8/80mm for Pentacon Six) here.

I agree with Stephan: Pentacon 6.

I used to own a KIEV-60 MF camera which used the Pentacon 6 mount. From your image I would say the breach-lock lugs, locating stud and aperture pin are all in the same position as Pentacon 6.

Its looks just like a praktina see the small lever?
