Museum Description:
"This barrel of this non-achromatic telescope is covered in black rayskin, while the four draw tubes are made of green leather and decorated with gold tooling. The lens holders and other fittings are made of ivory, but all the lenses and eyepiece fitting are missing. Black rings around the draw tubes indicate the optimum length in use. A handwritten inscription around the base of one of the draw tubes names 'George Willdey', an optical instrument maker working in London in the early 18th century" (Royal Museums Greenwich).
