Hi Graham, Just to confirm what Ugo said. My Good frien Bob Letsche, formerly a great contributer to this site sent me these pics and explanations. He has made a very comprehensive picture chart of Contax and Kyocera models.
"Sounds like a circa 1979 "Fundus" Scientific/Medical variant of which there were quite few made for use by Zeiss and others for Ophthalmic purposes. It's on the chart. Cheers, Bob.
This last one is a little odd in that it has the Sci/Med front shutter lock but may not have the deeper shutter release shroud, as seen on other sci/med. It can be seen on the top shot above.
Note the early data back
Cheers, Bob."
