Bolex projector DA37

Model DA-37

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.
