- Description
- This adjustable string model has four round horizontal brass discs and a central base, spindle and handle. There are holes around the edges of the discs, and the middle one may be rotated. The strings of the model pass through the holes. In one position, they form a cone and a cylinder. In another, they form a hyperboloid of one sheet.
- The model has no maker's mark.
- This model follows the design of an Olivier or Brill model of a quadric surface. Compare to the model by L. Brill with museum number 1985.0112.009.
