Hi Brian,
I own an MF and two MF-1s but don't know much more than you. I do
believe that it is meant for some sort of endoscope/gastroscope set up which
would bayonet on to the end of the lens/adapter. Only one of mine has the
endoscope adapter and it is different to yours - shorter and with the
designation AP-K55 so I guess there were different focal length adapters to
vary the magnification.
A couple of other things - you say it has no focussing screen, but does it have
the semi-spherical protrusion below the prism? If I mount a lens on mine I
still get a focussed image. The other thing is that although based on the ME it
has the two pins on the back for the old-style databack which would make it the
only ME style body to do so.
