Brandis Wye Level

This level, which dates from the period 1875–1890 when F. Brandis & Co. was trading as such, is similar to the "18 Inch Patented Improved Wye Level as Made for U.S. Engineer Corps" that Brandis advertised in 1881, and that cost $140. The patent in question (#201,155), granted to Brandis on March 12, 1878, described a spindle attachment that connects the telescopic level to the leveling head. The compass on this example is marked "F. BRANDIS & CO., NEW YORK 531." A label in the box dates from the period 1878–1879 when Brandis was in business with Richard Teckritz. It reads: "BRANDIS & TECKRITZ, MAKE in the most accurate manner, ALL KINDS OF MATHEMATICAL & ASTRONOMICAL INSTRUMENTS. Theodolites, Transits, Leveling Instruments, Sextants, Quadrants, Etc. Etc. All kinds of Instruments re–divided, re–paired and adjusted. No. 55 FULTON ST. NEW YORK."
