The Model K was a higher-spec model in Detrola's lineup of bakelite cameras for 3×4 cm images on 127 film. In 1940, the Model K was offered at a list price of USD $22.50, almost double that of the Detrola Model G. While it shared the extinction meter of the Detrola Model H, the selling point of the Model K was its f/3.5 lens, about 2/3rds of a stop faster. When this is a Wollensak Velostigmat rather than an Ilex Anastigmat, the camera may carry the designation Model KW.
