Thanks for the swift response.  I have taken a couple of pictures which I will try to attach


Yes, it's a stereo camera, for making 3D pictures. This is an Ontoscope, a very typical European style stereo camera, made by Cornu of France in the 1920's, for 45 x 107 mm exposures on glass plates. There are several different versions, and you have the most basic model for amateur photographers. The "Manoscope" name was used by certain exporters. The Ontoscope is a fairly generic design, it looks and operates like MANY other 1920's-1930's stereo cameras from dozens of other European camera makers, and they remain quite common. In truly excellent complete and clean and functioning condition, these sell month to month on eBay in the $175-$250 range. Your example looks clean and complete enough, and I'd hazard to guess it still works (they're built to last), so I'd guesstimate a fair market value right in the middle, about $200-$225.

I'm an expert on all types of antique and classic CAMERAS, vintage PHOTOGRAPHS, and the HISTORY OF PHOTOGRAPHY. Everything from ancient box cameras to modern single-lens-reflex; from simple Kodaks to sophisticated Leica and Nikon; from glass plates and roll film to movie and 35mm; from daguerreotypes and tintypes to the black & white images by the 20th century masters. I can identify and appraise, explain techniques and processes, offer insights on restoration and preservation, and provide guidelines for buying and selling.


I've been a professional photographer and a student of the history of photography for over 30 years. During that time my collection of vintage cameras and photographic paraphernalia has grown beyond 2000 significant pieces. I've published nearly 70 articles in the field, including 16 in the popular "Buying Classic Cameras" series for PHOTO SHOPPER MAGAZINE from 1995 to 1997, I'm currently a contributing editor for CAMERA SHOPPER MAGAZINE and McKEOWN'S PRICE GUIDE TO ANTIQUE AND CLASSIC CAMERAS, and I've written numerous entries for WORLD BOOK ENCYCLOPEDIA. Portions of my collection have been displayed in museums and special exhibits in the past two decades, and many of the items were photographed as illustrations for books. In 1985 I founded the International Photographic Historical Organization (InPHO), which eventually evolved into its intended purpose as the best first resource for information on the history of photography. I'm also a founding member of several e-mail forums dedicated to specialized areas of photography, and I'm the moderator of the Internet Directory of Camera Collectors (IDCC), which remains the largest and most successful such group in the world.
