A very fine early 19th century brass Ellipsograph.
This English ellipsograph comes in its original oak box. It is inscribed 'Invented by Cubitt and Made by W. Harris & Co., 50 High Holborn'.
Cubbitt received a silver medal for this design and it went into production. Set on two feet with an adjustable drawing arm below, and the operating handle above the circular trammel for drawing ellipses and circles. The maker's label can be found on the inside of the lid.
