Notes and Comments
The Model D was a dual guage projector with interchangeable sprockets, reel spindles and gate. First produced in 1931, it saw several modifications over the next few years.
1931 -- 9.5mm/16mm Dual-film Format
The original Model D projector used a 250 watt lamp.
1933 -- 9.5mm/16mm Dual-film Format
The Model DA was designed with the addition of a notch title stop device for 9.5mm film. It also used a 250 watt projection lamp.
1937 -- 9.5mm/16mm Dual-film Format
Possibly referred to as a DA II, it was an improved version of the DA projector, with better cooling & a 400 watt lamp. To accommodate a larger shutter blade, the shape of the chassis was modified slightly with a taller, more circular top. (pictured at right)
The Bolex Model D was only slightly more expensive than the Model C. Several advertisements in American publications in the early 1930s list the price as $109.
