I believe this Gurley Light Mountain Transit was made in the early 1900s based on the Aregood Gurley Transit Dating Guide. The transit does not have a serial number, so it was made before 1908. But it has some features that first started showing up in 1901 or so.

The transit is in really nice shape as the pictures evidence.

The box is also in nice shape, and includes a nice Gurley label. The Gurley label lost its adhesion however while I was taking pics. You should be able to reinstall the label without too much trouble.

The box is in good condition as it is covered with leather. The leather is about 3/4 present but falling apart on the top.

This light mountain transit has a 4 inch needle and an 8 inch telescope.

Everything seems to work really nicely.

Strong - sharp optics. Crosshairs and stadia wires are present.

There is no binding on the horizontal or vertical plates. The needle lifter works fine. The level vials hold liquid as shown in the pictures.

The transit comes with a sunshade and a few small tools. There appears to be a steel plumb bob in the box as well.

Please take a look at the 360 Degree View of the instrument, and zoom in on various views. This instrument merits a close inspection.

I have a good deal of information about Gurley, including some production information, posted on my Gurley Maker Webpage.
