Notes and Comments
The 18-5 Automatic featured auto threading of film through the gate and sprockets, but otherwise incorporated the same design of the original 18-5 projector.
The speed selector knob, on this and later 18-5 models, was changed from red colored plastic to luminous plastic ("glow in the dark"). A choice of lenses was available at purchase, and a plastic zipper cover and Bolex 400' plastic reel with case were included.
Serial Numbers and Dates of Manufacture
The serial number on 18-5 Automatic projectors is located on the bottom of the base, directly behind the front leg; it can be used to determine the year in which it was manufactured. The table below lists the range of serial numbers allocated to the production run of both 50 Hz and 60 Hz variations of the "automatic" threaded 18-5 projector.
