Chronology of cameras Graflex 

Traduction de Manuel M

Attention with confusion! There is Graflex RB series B and Graflex series B. first is Revolving Back (RB) i.e. that its back is rotary, which makes it possible to pass easily from a vertical centring to a horizontal centring. It is easier than to turn the camera.. The Graflex series B is with fixed back.

Although one does not see it on the picture, it is a reflex camera, whose centring is done in a large foldable cone which avoids the parasitic lights reaching the ground glass.
It seems that the viewfinder that one sees on the hood is an addition part, because normally at this place is fixed the handle of transport and who facilitate the opening of the hood.
The lens is protected by a metal cap. At the time of the focusing, it is the metallic plate on which the lens is fixed which moves, at the end of a small bellows.
