Wollensak Optical Co. (Rochester, NY)

Un-named Stereo Shutter - c. 1905



Notes:  This was installed on a 5x7" Gundlach-Manhattan Optical Co. Wizard View Camera Variation 3.  The shutter has a black speed dial that reads "Manhattan Optical Co.", and the shutter itself is engraved " Wollensak Optical Co. / Rochester, NY / USA".  The shutter apparently was made for Manhattan Optical Co. under contract by the Wollensak Optical Co.
