The “Three-D” from Coronet is a stereo camera for pairs of photos on 127 film. The early versions have a ribbed bakelite case, although these were supplanted by the smooth case shown here. Later models have a speckled bakelite body. The camera employs fixed focus lenses with a single shutter speed, and the shutter release is located on the right side of the camera, towards the front of the body.
Switching the camera to take eight single (non-stereo) images per roll is possible by blocking one lens with a built-in internal metal cover.
A British stereo camera from the fifties. This camera takes stereo pairs on 127 films. I particularly like the binocular finders.
You’ll see other variations of this camera with different finder arrangements, and you might notice the illustration on the cardboard packaging shows a single direct-vision finder. The earlier cameras also had a little reflex finder with the front window where the round ‘coronet’ moulding is on this camera.
The back of the camera has brief instructions on using the camera to take single exposures.
