Museum Notes:
"The barrel of this non-achromatic telescope is covered in sharkskin and is decorated with gold tooling. There are four draw tubes, each covered in marbled paper. Gold-tooled stop lines around the draw tubes indicate the optimum working length of the telescope. The other fittings and screw-on lens caps are made of ivory. Two inscriptions appear on the telescope. The maker's details are engraved on the objective lens: 'FRANC SANSEDONIUS. 1730 NEAPOLI'. In addition, the words 'Questo va di sopra', meaning 'this end up', are handwritten on the optics combination, presumably to ensure that it is assembled the correct way round" (Royal Museums Greenwich).
