Forgive me, but there are examples of the CZJ Tessar 50/2.8 which would need
more than a little filing of the mirror.  

Here's mine in profile:

And face on - see, CZJ Tessar 50/2.8 (well, you can just about see through
all the noise, but that is an illustration of how deeply recessed is the
front element):

Of course, it's a macro-Tessar, most at home on one of these:

It's a Kopil bellows with tilt on the front standard, and rise on front and
rear standards, in Exakta mount, with Exakta-to-4/3 adaptor. Not easy to
find, but a whole lot cheaper that a Nykon PB-4!

But this CZJ Tessar is not preset diaphragm - fully manual, no click stops.

There is only reported CZJ 50/2.8 preset and it does hit the mirror.
I think that's the one we're speaking of.  But I'd guess a little bit of
filing off the bottom of the rear cell would likely fix that.
