This is a simple, yet serviceable camera constructed
by hand by a cabinet-maker. Which maker is unknown, as with most
such cameras. The hand-cut dovetail joints can be seen along the
bottoms of the standards. The rear has a hand-cut tongue & groove
joint. It is most likely of English origin.
The lens is a Holmes, Booth & Hayden (NY) radial
drive with long lens-shade, c.1850.
The sliding-box was used as a focus mechanism in the
early part of the photographic era, when camera-making was attempted by
craftsman used to making chests of drawers. Its appeal was that
such a camera could be made entirely by a cabinet-maker, whereas
bellows-making was a specialty foreign to wood-working circles. By
1860, camera making manufacturers (who had their own in-house
bellows-constructors) began to dominate camera production, and the
sliding-box design fell out of use.
