une, 1923 School Department 311 THE NATIONAL PORTABLE PROJECTOR Model "B" THE NATIONAL SEMI-PORTABLE PROJECTOR Model "S" THE NATIONAL PROJECTORS shown here are machines of real merit that any owner will be proud of, due to their continuous and faithful performance. Both models of "NATIONALS" project successfully attached to any voltage, such as is used in a City, Country Town or where Storage Batteries only are available, with equally good results, projecting a clear, sharp, steady, flickerless picture of ample size, equal to theatrical quality. The feature of a STILL PICTURE is incorporated in both models for the convenience of the Educator, Lecturer and Salesman. Model "B" is the projector wanted for portability, being compact, light in weight, simple, but durably constructed and very easy to operate. Model "S," the MONARCH OF ALL SEMI-PORTABLE PROJECTORS, has every feature incorporated in its construction that is now standard equipment in the Professional Types of Projectors. Can either be mounted on floor with extension legs at any angle, or can be placed on a table. Sufficient illumination can be obtained from this Projector to be ample for the most severe projection. Write for circulars and descriptive matter on our projectors, which we know will be of interest to you. ENERGETIC SALESMEN AND DEALERS WANTED FOR OPEN TERRITORIES THE NATIONAL PROJECTOR & FILM CORP.
