The Brownie Fiesta R4 has a molded plastic body with an aluminum lens plate and a clear plastic escutcheon. This simple camera has a medium sized optical direct vision finder and a fixed focus meniscus f/11 lens. The Brownie Fiesta R4 had the addition of a flashcube socket which was considered an improvement over the single bulb flash attachment available with all of the other Fiesta models. Other features are the red window in the back for frame counting with use of the numbered paper backing of the film, 1/40 of a second shutter, a manual flash cube socket on the top, frame advance knob on the bottom of the camera, and uses 127 size roll film. It was made by the Eastman Kodak Company in Rochester, NY, USA and originally sold for $9.00. It is unclear how many were produced but it is safe to say the hundreds of thousands. The flash unit used two PX825 mercury batteries for power that were discontinued for obvious environmental reasons. There are a number of replacement batteries like the EPX825, S825PX, LR53, BLR53, and the KA825 Silver Oxide 1.55V Battery. The camera did not have any double exposure protection and was only produced from 1966 to 1969.
