Drawing Instruments
Drawing Board. I inherited this Drawing Board from my father, Enoch Cordon. It is unusual in many respects. There are two built in clamps to hold the paper in position on the central circular board which can rotate and has an external ring marked with 360 divisions so that the entire board can be rotated to any desired angle. The board is counterbalanced, as is the set square allowing them to be adjusted to a desired position.
Eco Bra, Dietzgen Proportional Dividers with Scales of Lines and Circles. This has Number 14 on the body. The Scale of Lines is used when dividing Lines into a required number of parts. The Scale of Circles is used when dividing the Circumference of Circles into a required number of parts.
