Mint 1909 Gurley Surveyor’s Transit & Case, Troy, NY w/Gradienter & History Docs

This beautiful optical instrument is a 1909 surveyor’s transit made by the Gurley company of Troy, NY. Gurley was one of the premier international optical instrument makers of the 19th and 20th centuries. They are still in business, although they stopped making surveying instruments in 1980.

It has an unusual optional attachment called a Gradienter, which aided in rapidly determining grades and distances. I have never seen this attachment on an antique transit before.

It also comes with a 1999 letter from “Gurley Historical Services” indicating age, model number, the original purchaser (Stoddard Bros. in Buffalo, NY on 9/16/1909) and several old catalog page copies which describe the technical aspects of the transit.

Considering it is 115 years old, this transit is in near mint condition. All the bubble levels are intact, the compass needle moves freely, all moving parts swing properly without any binding, and the optics and crosshairs are good. There is some tarnish on the exposed silvering on the elevation circle, which is to be expected. The rest of the silvering is quite good, as shown in the photos. It appears it saw very little use.

It comes with the original fitted, dovetailed wooden case, with the original Gurley labels inside. The instrument is about 16” tall and about 13” in length. The wooden box measures 16” tall by 13” wide by 9” deep. Total weight of instrument and case is about 30 pounds.

This is a striking and rare example of true American craftmanship from a bygone era. It’s beautiful in its workmanship and rich in its history.
