Arm Drafting Machine
All i know about this product is that it is a tool of engineers. Please see the pictures to see all the items included in the package. Please do not ask me to identify them. Everything is brand new and will come in the original box. Below is what it says at the back of the instructions for mounting and adjusting sheet:"Your PARAGON III Drafting Machine will provide you with long lasting service. Its horizontal and vertical motions are smoothe and silent at any board angle - 5 to 8 degrees varying with surface, up to 15 degrees with counter-balance spring. When it is mounted to the drawing board, the scales will cover over 95% of the board surface.All controls are conveniently located to reduce the number of hand and arm movements - thus drafting fatigue is kept to a minimum."Good luck.
