If you are pulling the camera to pieces anyway, it should be fairly easy to measure the flange distance yourself.

+1 again. There is NO FLANGE. The lens is an integral part of the body, so where the flange ends up is a function of how you slice it....

Measuring from the film plane to the rim that holds the rear element is quite easy. Set the lens to infinity and use a piece of glass or metal on the frame window near center and subtract its thickness of the measurement you get. It's not a flange film distance as there is no "flange" in that sense in a compact 135 camera. Conversion design should allow some tweaking for infinity calibration.

I suspect it's too short for tilt/shift on MFT, but maybe not?

On MFT it will be hard for tilt/shift I estimate, too short distance from the lens rear to the sensor to suit the MFT register distance of 19.25mm. Probably at most 5mm to fit a shift/tilt mechanism. The lens is sort of a Tessar design, fixed focus, aperture probably primitive as well as it is linked to two ISO settings. Fixed 1/125 sec shutter time. No real exposure measuring but a low light warning.

It seems Andy Warhol was fond of a sister camera model, that usually says enough for me about the technical aspects.

The camera that really got me started was a Konica C35. Great camera. In fact, I won my first photo contest with a rather cliched shot of a sailboat that I took with my C35....

Unfortunately, mine was stolen decades ago. However, I bought one a couple of years ago thinking that maybe it could be adapted in some way -- hopefully not as challenging a conversion as this . I was actually thinking about using it with a LED array as both a low-res sensor and a projector... I even had an undergraduate senior project team work on doing that, but they ended-up targeting a 6x6cm TLR and didn't get very far with the project....
