Photography/German Knox Folding Plate Camera


I have found a 4 x 5 folding bellows/wood box camera with a simple scissor shutter on the outside of the lens board - there is a ivory label that says 'KNOX' - I don't know if that is the maker or model name - it has a ground glass on the back - appreciate any help in identifying the maker, year and value -  thanks in advance for your expertise - Andy


Hello Andy,

The Knox is a simple self-casing folding bellows camera, made by Emil Wunsche of Germany around 1905, for 9 x 13 cm exposures on glass plates.  It's a fairly uncommon model, especially in the United States (it was never imported here), and complete intact original examples like yours can sell for upwards of $300 in today's collectible camera market.

Best wishes,

David F. Silver - President

I'm an expert on all types of antique, classic, and contemporary cameras, as well as the general 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. I can identify and appraise them, explain how they work, and offer insights on their restoration and care. I can also provide historical background on vintage cameras and equipment, and guidelines on their purchase and sale.


I've been a professional photographer and a student of the history of photography for nearly 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.
