Adams Reflecting Telescope

This brass Gregorian telescope dates from the last quarter of the 18th century. It has a metal primary mirror 2⅜ inches diameter, and a smaller secondary that is adjusted by the rod that runs along the tube. The stand is adjustable in altitude and azimuth. The “G. Adams N˚ 60 / Fleet Street London” signature could refer to George Adams or to his son of the same name, both of whom worked at this address.
