DescriptionTelescope for transit, no model number, made by Keuffel & Esser Co., [Hoboken], no date, circa 1950s-1960s. Metal, brass with green Hammerton finish, and glass, ca. 9-1/2" long x 5" wide mount. Lens cap. This is probably the telescope, only, from an instrument (jig transit?) made by the Optics & Metrology Division of K&E. It has no markings identifying it as made by K&E including model or part number, but the style and finish are distinctively of that company. Further research may determine specific model. Item is for study purposes. Focusing knob on top; two trunnions with non-ferrous bushings for mounting; threaded posts on bottom for attachment of level.
