Very Nice Surveyors' Transit with Original Box and Tripod

This is a very nice Gurley Surveyors' Transit Model 77, complete with original box and tripod. This transit is the a single vernier reading to a minute version, and includes options such as the 4.5 inch vertical circle, telescope level and a 5 inch needle.

The optics work on this instrument, and the instrument turns freely.

The transit includes the original tripod and box (which has been refinished). Shipping a tripod is expensive - please deduct $100 from the purchase price if you do not want the tripod.

Attached below is a page from the 1897 Gurley Catalogue of Instruments showing the different models Gurley offered, with the Model 77 reflecting the instrument offered here.

The Gurley Instrument Manuals contain a great deal of helpful information about Surveyors Transits. Here is an extract from the 1895 Gurley Manual discussing the Surveyors Transit.
