Manufacturer:
American Optical Co. New York, NY factory Scovill / American Optical made a number of
of cone or tapered bellows cameras. The following is an excerpt
from
American Optical/Scovill Back Focus Tapering Bellows Field View Cameras - Chronology and Design
detailing the history of Scovill/American Optical camera models of this basic
type.
Flammang's Revolving Back View
Camera Back Focus Model - Variations:
There are currently
at least five
variations of Flammang's Revolving Back View Camera Back Focus model,
and one counterfeit copy. The differences between the
variations are due to 1) push-pull or rack and pinion focus, 2) whether
the vertical (forward-back) swing is hinged at the bottom or at the
middle of the rear standard, and 3) lacquered brass or nickel-plated
brass hardware:

Variation 1.0:
1) push-pull focus having a lever in the rear to secure it, 2) vertical
swing hinged at the bottom of the rear standard (as in catalog
engravings) and 3) lacquered, draw-filed brass hardware. This is
the camera configuration as depicted in the engravings in
American Optical/Scovill
catalogs and other advertisements.

Variation 1.5:
same as Variation 1.0, except that it has rack and pinion focus rather
than push-pull focus. Thie example of this Variation also has its
label altered to indicate that it was made for
W.H. Walmsley & Co.
instead of the usual American Optical
and Scovill Mfg. Co.
label. Additional examples will have to be seen of this variation
to know whether the configuration was specified by Walmsley, or whether
the variation was already being offered by
American Optical.

The revolving back was patented by Mathias Flammang 21 Aug. 1883 (US
283,589), one of many patents granted to Flammang while working for
Scovill Mfg. Co. The revolving back
could be had either on a back focus or front focus design. It is one of
the longest lived Scovill designs,
being introduced in 1883 (The Photographic Times and American
Photographer, Vol. XIII, No. 149, Scovill Mfg. Co., May 1883, p.
205 ), and carried in catalogs and other advertising literature until
approximately 1898.
