Mystery Copal 1 Aperture Scales

[Steve Goldstein]

There's a nice set of factory scales on a Copal 1 shutter I recently acquired, but I have no idea what lens they might be for. The maximum opening is f/4.5, with graduations in 1/3 stops to f/45. Both are marked 0005.056 and the notation "Lens Made in Germany". I compared them against the scales on a 210mm something-or-other and they're just about 1 stop different.

Does anyone have any ideas? 150mm f/4.5 Xenar maybe?

Thx.

Perhaps a 90mm F4.5 Rodenstock Grandagon.

I actually picked up a used Copal #1 that has the same scale number (005.056) but only in full stops. Engraved on the back of the shutter is 90mm Rodenstock Grandagon. I wonder where all the Grandagon glass is going

Anyone want to trade for some 210mm scales (0011.064)?

Thanks guys, now I'm all set in case a set of 90mm f/4.5 Grandagon elements come my way. The wealth of knowledge out there always amazes me.
