Philadelphia Stereoscopic Box, New
American Optical Co. New York, NY factory
Date Introduced: 1870 ;
Years Manufactured: c.1871-1882
Construction: rear focus
via push-pull with fine focusing screw; single swing; reversing by
two tripod mounts; three-piece lens board
Materials: mahogany body; cherry base; black fabric bellows;
Sizes Offered: 4x7; 4x8; 5x8
Notes: Described in the
references as being the same as the Philadelphia Stereoscopic Box, except for
the swing configuration. The rear of this camera
is reported in the references as a design which swings inside of the main box, while the "old"
version swings outside. However, American
Optical did not help
to distinguish the difference by using the same
engraving for both cameras. More confusion is added by Wilson, Hood & Co., who use
same engraving for
Stereoscopic Boxes on p. 33, while advertising the
Philadelphia cameras on the next page. The engraving
below, while not a stereo format, shows the basic configuration of a swing
inside the main box.
