THE CORRESPONDENTS' CAMERA. ER TRIPOD

Originally made for the use of Newspaper Men in South Africa, and since used all over the World,

THIS Camera has been designed for the use of correspondents,

artists, and other travellers who, while requiring a Camera possessing the greatest stability, cannot spare the space for a regular field camera in addition to a hand camera. It is made o. the best mahogany, carefully finished and covered with hard morocco leather, or polished in natural colour or ebonised at the same price. It is admirably adapted for Telephoto work. Owing to the use of wood instead of metal, wherever possible, this

camera is lighter than many of less substantial make. EACH SIZE PERMITS OF THE USE OF THE SINGLE COMPONENTS OF A STIGMATIC OR OTHER CONVERTIBLE LENS. PRICE, including 3 Double Slides, but I 44 by 31.
