Barry, I might have some adverts for the Reflex Primar if you'd like scans.

So you've discovered the beauty of European Focal Plane shutters, dual curtains, sophistication, quite the opposite of Graflex. I don't think people realise that the various early 1900's European shutters are like scaled up 35mm cloth shutters, but very much earlier.
