Goltz & Breutmann "Mentor” II 9 x 12 Folding Strut Camera, also called the "Mentor Focal-Plane Camera,” Nr.27 with G. Rodenstock 165mm Doppel Anastigmat Eurynar f4,5 lens (Nr. 231075). The shutter is wrinkled and mechanism sticky, and the lens hazy with light cleaning marks. Both the film back and viewing back bear the matched serial number "27,” making this example likely to have been made in the earliest years of the last century, perhaps even as early as 1900.
