Koni Omega focusing knob

Did anybody ever seen a focusing knob for the Omega rapid cameras that is marked in meters or do these exist only with scales in feet?

Also, as good an idea the 9 holes for keying which back you have used is, how you cover the first one?

You could use black RTV to close the ID hole.

I just checked 2 of my Koni's and they are in feet only. This camera was sold in Japan as the Konica Press. That would have meters. If you take some of the flash calculator cards (the white cards on the focusing mount) you could make a meter scale out of it. It would be lens specific but you would have a scale.
