Thornton-Pickard Ruby
The Ruby is a wooden folding field camera made by Thornton-Pickard from about 1890 to 1907.[1] Intended for use on a tripod, the folding bed includes a turntable. The design was changed to make the camera also usable as a hand camera.[2]
McKeown states that the camera has a 'Ruby' Rapid-Rectilinear lens.[3] This is mounted on a Thornton-Pickard roller-blind shutter on the front standard.
The Royal Ruby is a very similar camera, introduced as a high-specification version of the Ruby (Notes at Early Photography describe it as the top of T-P's range[4]) in about 1900,[5] and continued in production for some years after the standard Ruby was discontinued. McKeown states that all Royal Ruby cameras are triple extension (allowing close focus, or long-focus lenses).[3] Examples exist with roller-blind shutters on the lens board,[6] and with a built-in focal-plane shutter.[7] Royal Ruby cameras have been seen in quarter- half- and full-plate, and 4x5-inch and (perhaps) 5x7½-inch (or 13x18cm) sizes. Notes at Early Photography state that 5x7½-inch and 8x10-inch cameras were introduced in 1907, when the quarter-plate and 4x5-inch sizes were discontinued.[4][5][8] There is also a half-plate stereo model.
The Special Ruby, strangely, was introduced as a lower-specification version of the Ruby, also shortly before the standard model was discontinued.[3] Wood and Brass shows an example from 1909-12, with a spring back (for easy insertion of dark slides in front of the focusing screen) and with triple extension;[9] the notes state that these features were among those left off the Special at first, and that they were reintroduced in about 1908, so the camera is very similar to a standard Ruby. McKeown lists the special Ruby as double extension.[3]
