The Royal Ruby was introduced in 1902 in either double or triple extension form. Sizes were 3 ¼" x 4 ¼", 5" x 4", 6 ½" x 4 ¾" and 6 ½" x 8 ½". The Royal Ruby was the top-of-the-range field camera from Thornton-Pickard, it was based on the Ruby with additional features such as rackwork to the rising front, rackwork to the rear standard and improved side swing (swing back). The rear standard could be brought close to the front standard for wide-angle work. A focal-plane version in the half-plate size was advertised for a short time from 1904. During this period a Ruby Rapid Rectilinear was the lens normally supplied with the camera.

In 1907 a new strut arrangement and front standard was introduced (BP 4515/1905) which allowed greater movement of the front standard. At this time 7 ½" x 5" and 10" x 8" sizes were added and the quarter-plate and 5" x 4" were ended.

Around 1909 an overseas model in teak with screwed joints was available. Brass binding was an option in either teak or mahogany. The improved version was offered with several lens options.

The lens on this example is fitted with wheel stops which is unusual for the period.

The diagram on the right, taken from the patent, shows the improved strut arrangement BP 4515/1905.

Image of Royal Ruby Triple Extension

Lens:
f5.6, 7" Ross Homocentric, iris diaphragm to f22. Serial no. 65076 (c. 1907).

Shutter:
Thornton-Pickard T&I shutter, speeds 1/15 - 1/75, T.

Construction:
Polished mahogany with nickel-plated fittings. Leather bellows with diagonal corners.

Format:
6 ½" x 4 ¾" plates held in double dark-slides.

Focusing:
Bellows to 21". Triple extension. Rack and pinion movement to inner frame and to outer frame, additional rack and pinion to move rear standard along outer bed.

Attributes:
Reversible back with spring mounted focusing screen. Plumb bob. Turntable in base. Slots for septum.

Movements:
Rising front, cross front, swing and tilt to back, tilt to front.

With:
1 double dark-slide (3/4).

This is an unusual model in having nickel-plated fittings, it has the early type front struts and probably dates to around 1907, the period when the new struts were introduced. The shutter has a transfer name plaque, no serial number, fine-cut finger joints and late type cog wheel with screw-on fittings. This late shutter could indicate that it has been replaced or that they were introduced earlier than previously thought (World War I period).
