Byers Cam-Trak I purchased a Byers CamTrak from a friend and included was these printed
documents that I wanted to share with everyone. This is valuable documentation for this unique Instrument.
The scanned Sales brochure, instructions, drawings and polarscope aligment information are below the pictures.

The entire package, Cam-Trak,12vdc to 12vac power supply, 3 counterweights, illuminated polar, Byers Cam-trak case and Documentation

A close up showing the illuminated polar scope with brightness control. This is the first, I have seen with a illuminated polar scope attached.

A close up of the Cam-Trak Unit. The only thing that needs work is the counterweights are scuffed up from being carried in the case without protection between the weights.

A close up showing the Cam-Trak packed in the carrying case. It even has the allen wrench to tighten the camera holding knob, and make adjustments for elevation
