Seneca's Box Scout No. 3 is a box camera for rollfilm. It has two reflecting type viewfinders, one in the top for vertical exposures, and the other in the side for horizontal shots. In the side is also the shutter release lever. On its top the camera has a leather grip and the aperture selector. There's no aperture scale so that you have to look which aperture appears in the front opening, the small, the medium or the largest one. The camera's lens is positioned behind shutter and aperture. Below the aperture selector is a little shifter to switch the shutter from "instant" to "bulb" mode. After opening four locks at the side that side plus the attached film holder can be pulled out of the camera to unload and/or to load film. The camera could be used with Eastman Vulcan film rolls of type No. 236 or No. 248 which might be similar to Kodak type No. 118 film for Kodak "No. 3" cameras. In its back is a red window. The camera is made of wood. Inside the camera the wood is painted black, outside it is properly coated with cheap black leatherette. In the camera's bottom is a tripod thread.
