Wye Level
Wye Level
- Description
- Although the Gurley firm did not begin using serial numbers until 1908, its level makers began stamping a serial number on the bottom of each baseplate in 1900. This level is stamped 2478, and is marked "W. & L. E. GURLEY, TROY, N.Y." Company records reveal that it is one off four identical levels that Gurley made for New York University in 1906. New, with tripod, it cost $110. The Bronx Community College, which had taken possession of the Bronx campus of New York University, donated it to the Smithsonian.
