Plotting protractor
This brass plotting protractor, used in a draughtsman's office, was made around 1850, probably by Gardner & Co., scientific instrument makers based in Glasgow.
The circular protractor has a pointer and an arm with a pricking point. Engraved by the arm is 'Gardner & Co. / 21 Buchanan St. Glasgow'.
The Gardner's family firm was established in 1799 by John Gardner, who had been James Watt's principal journeyman before setting up on his own. The firm became prolific makers of scientific instruments during the 19th century.
