The Imperial Mark 27.
The layout is vaguely related to some of the Kodak Star series, with the film advance winder in the base, an aperture selector (marked COLOR/B&W) below the lens and horizontal lined styling on the back. For the people who cannot find any information on a Tower (Sears & Roebuck Co) camera that looks like it's twin, it's the same camera. It was produced in 1964 by Imperial for Sears & Roebuck under the name Tower Hide Away.
