FINE VICTORIAN BRASS PROTRACTOR, English, c. 1862, signed “J. Gargory, 41 Bull St., Birm’m.” This 6-1/4″ (16 cm) diameter full-circle protractor is divided every degree from 0° to 360°, and back again, boldly labeled with easy to read numerals. Both crossbar and circumferential edge are beveled down to the surface of map or chart. Condition is fine, retaining much of its original lacquer finish.
James Gargory is listed as optician, jeweler, goldsmith, and mathematical, mining, surveying, and optical instrument maker. Clifton gives working dates of 1835 – 1862, always on Bull Street in Birmingham, but at the present address only in 1862.
