The Kodak Jiffy is a collapsible, medium format camera produced by Kodak between 1937-1948. There are two different film formats of Jiffy, as well as two variations in each format. The Jiffy Six-16 was produced between 1933-1937, and uses 616 film to make a 2.5x4.25 inch image. The Jiffy Six-16, Series II was produced between 1937-1942, and has a black leather front instead of the Art Deco design of earlier camera. The Jiffy Six-20 was produced between 1933-1937, and produces a 2.25x3.25 inch image on 620 film. Finally, the Jiffy Six-20, Series II was produced between 1937-1948, and has a black leather front instead of the Art Deco design of previous version.
The Jiffy resembles most strut-folding, medium format cameras of the era. When collapsed, the camera is very compact and can fit into a coat pocket. A button on the camera body releases the front standard, allowing it to expand out. Two bright finders are situated for composing with the camera either in landscape or portrait orientation. Shutter has a single fixed speed of approximately 1/50th of a second, but also features a switch for Time mode. Aperture selection is similarly limited, most models have a pull lever that changes aperture between f/8 and f/11 - though some models are reported to have f/16 as well. Focusing is done via zone on the lens itself, with one setting for 5-10 feet and a second zone for all distances beyond 10 feet (infinity).

We were looking at this Kodak Jiffy camera and started wondering just what a Twindar lens was. As far as we can tell, the Twindar name was only applied to the Kodak Jiffy cameras (we're sure there are others, but the Jiffy was the only that referenced Twindar). It is basically a periscopic lens design. ⠀
Periscopic lenses are noted for having two equally convex meniscus elements arrayed symmetrically with an aperture mechanism between them. They were cheap and easy lenses to make, hence many box cameras and vest pocket cameras sported various periscopic lenses. The first periscopic lens was apparently made by Steinheil all the way back in 1865.
Maybe that info will be useful someday at camera trivia night (but somehow we doubt it). Unless you're the one asking the question...
