This non-achromatic Galilean telescope has a dyed rayskin (shagreen) barrel and a single leather draw tube that is decorated with gold-tooled motifs. The mounts are made of turned horn while the other fittings are silvered brass and include sliding objective and eyepiece lens covers. Stop lines on the draw tube indicate the optimum working length of the telescope.
