Well, my idea was, that it is
a japanese subminiature SLR with Olympus endoscopy mount and zoom lens
Not clear to me was whether that is a peeping hole at the back (the photo in that link now show that it is, likely to show a code)
Neither clear to me was the function of those markings at the viewfinder. Kino's idea is that these are color codes taken from the cassette, visible in that peeping hole, to set an autoexposure function. Makes sense. But a mechanical coding at the cassettte would be the better way (likely patent issues).
Still not completely clear is transport and shutter cocking. Must be motorized, with voltage feed through that mount.
What a great find !
