Although there is no name or markings on the camera it is a Junior Special Ruby possibly made for a retailer to sell under another name. The Junior model was brought out in 1924 as a cheaper model in the T-P range. It remained on sale throughout the 1930s.

When introduced a reversing back was fitted, around 1926 this was replaced by a revolving back. Other modifications at around this time were a raised square plate carrying the shutter tensioning knob. A pivoting catch was added to lock the release lever.

By c. 1930 the draw slide, when removed, fitted in a slot in the front of the focusing hood. A swing front was offered at extra cost around 1935.

Sizes available were: 3 " x 2 "; 3 " x 4 "; 4" x 5" and 9 x 12 cm. A large number of lenses was available up to an aperture of f2.5.
