I have never seen another example of this camera and can't begin to speculate on it's rarity. This is a later model Moy & Bastie, at least later than the other examples you see on my web site. My guess it is near 1918-19. I base this date on the all gear drive mechanism in this camera. I feel it must have been manufactured after the end of World War I. World War I had the unfortunate circumstance of causing the end of most innovation and the loss of most creative thought processes while machine manufacturers were focused on weapons production for national survival. This camera is all gear driven as opposed to chain driven, as in the other examples of Moy cameras you can see in the gallery area of my web site.
