Description
For sale is the nice Symmetrical Brass Lens from around 1890's - 1910's. It's stamped on the exterior saying 'Symmetrical 6 1/2 x 8 1/2'. I measured the focal length of this lens to be around 9 inches (230mm). Lenses are super clean, no scratches, haze, separation or fungus. Diamater of the lenses are around 33mm. Easy to removed from the barrel. The lens is set in a Unicom shutter (large size), the aperture blades of the shutter are removed. Comes with retaining ring to mount on lensboard.
