The classic and innovative Sanderson strut arrangement was patented by F. H. Sanderson on 10 January 1895. The designed and Sanderson name was quickly purchased by Houghtons of London who began mass-producing the field Sanderson and, from 1899, the hand camera. The patent covered a number of features: a method of supporting the back or front of a camera which allows them to be fixed at any angle or adjusted for focusing; and lens board which is provided with a rotating panel in which the lens is mounted eccebtrically; and tapering bellows.
This camera predates manufacture by Houghtons and therefore can be considered one of the earliest known Sanderson cameras.
