Public Notes:

"The barrel of this non-achromatic terrestrial telescope is covered in a dyed rayskin. while the four draw tubes are made of green vellum decorated with gold-tooled motifs. The brass fittings include a sliding eyepiece and objective lens covers. The maker's name appears on the smallest draw tube as 'STERROP LONDON', probably referring to George Sterrop, who worked in St Paul's Churchyard in London in the 1740s. Stop lines, shown as rings of dots drawn onto the draw tubes, indicate the working length of the telescope" (Royal Museums Greenwich).
