A 1 1/4-inch Dudley Adams Patent refracting telescope, English, circa 1800,

signed ADAMS, New Patent Portable Telescope No. 60 Fleet Str. LONDON, with seven brass draws, shagreen covered tube and covers to eyepiece and objective, extended length 19in (48cm)

Footnotes

The patent obtained on 30 May 1800 by Dudley Adams included a new form of spring fitted inside the draw tubes to keep them steady when drawn out. This allowed more draw tubes to be used, reducing the overall length of the telescope when closed.
