Builder's Transit


Convertible Transit Level with a "C. L. BERGER AND SONS, INC. BOSTON, MASS. 62282 MADE IN U.S.A." inscription. Berger introduced this form in the early 1950s, describing it as a "modern, practical and sturdy instrument, precision engineered for the requirements of the contractor and builder." This example belonged to Charles H. Rutter, a contractor and builder in southern Prince George's County, Md. Its horizontal circle and vertical arc are divided to single degrees, and read by verniers to 5 minutes.
