The earlier Ruby Reflex was renamed Ruby De Luxe around 1922. In 1925 'Speed' models were introduced with f2.5 and f3.5 lenses. 1927 saw the introduction of the Universal Speed Control, this allowed slower speeds to be selected after the shutter had been tensioned, previously the shutter had to be released and reset. A pocket in the focusing hood to hold the draw-slide was included in 1930. In 1932 a two-way swing front was added, metal girders connected the front standard to the body rather than the wooden base previously used.

A wide range of lenses was listed. A time valve could be fitted giving shutter speeds down to 3 seconds. The position of the lens-box retaining clamp differs between early and late examples.
