The Ehira Six and Astoria Super Six are horizontal folders, strongly inspired by the Super Ikonta. The body is perhaps based on the body of the Weha Chrome Six rigid model.

There is a combined range- and viewfinder. The viewfinder window is offset to the left and the second image window is to the right. The lens is front-cell focusing and the rangefinder coupling is optical, with no mechanical linkage: the front element of the lens is geared to an optical device placed in front of the second image window and focusing is controlled by a small wheel protruding from the lens casing. It is not known if the optical coupling lens is a wedge prism as on the Super Ikonta and other Zeiss Icon models or a laterally moving lens as on the earlier Weha Chrome Six, also made by Ehira.
