Gurley Burt Solar Transit

The Gurley Light Mountain Solar Transit offered here is a wonderful example of one of the most important surveying instruments ever made for public land surveys. Having looked thru a great number of General Land Office field notes for the public land states, I estimate that US Deputy Surveyors and Mineral Surveyors used a Gurley Light Mountain solar transit in approximately 40% of the public land and mineral surveys from 1880 thru 1910. That's just sheer marketplace domination when you consider all of the different solar compasses and solar transits made by instrument makers.
