The Ensign Autorange 16-20 is a British coupled rangefinder roll film folder from the mid 1950's. It's equipped with the well respected Ross Xpres 75mm F3.5 lens. This one came with its ever ready case in an Ebay lot with a few other cameras. Houghton-Butcher who traded as Ensign, never made a 35mm camera, and seem to have disappeared by around 1960. My Wallace Heaton Blue Book of 1955 gives the price of the 16-20 as thirty nine pounds and fifteen shillings. There are other Autorange cameras for different sizes, the 6x9 820 being the most desirable apparently, as they can go for thousands. As so often, despite what some say about ever ready cases, this one had kept its contents in lovely condition. These cameras have a similar rangefinder coupling syaten to Super Ikontas, with a rotating optical wedge on the end of an arm – upon opening the camera, you have to move the arm into its operating position.
