Notes and Comments
The Bolex M-8 projector was designed to run off a mains power supply of 110-125 Volts.
The earliest M-8 projectors were olive colored, with a slightly textured finish, and featured the Paillard over Bolex logo with black control knobs. In 1956, the style was redesigned with a two tone grey and silver finish, with a smoother surface and red control knobs. Most of the late models have the Bolex over Paillard logo.
In 1959, both models included a built-in stroboscope which allowed the projector to be adjusted to an exact speed of 18 frames per second.
