Unless you used a Corfield Periflex, which used a Leica thread & register
but didn't need the rangefinder cam because it had a drop down periscope
with rangefinder-type focusing wedge. It retracted out of the way as you
pressed the shutter release.

A Visoflex housing, but the lenses and fittings were different from anything
else.

The original Russian Zenith s.l.r. did, but the register was greater to
allow for the mirror.
