I believe this Gurley Light Mountain Solar Transit was made in the early 1890s based on the Aregood Gurley Transit Dating Guide. This instrument is missing its solar apparatus, however.

I purchased this transit and the Light Mountain solar transit I am offering as one of my Instruments of the Month. At the time of purchase, the Burt solar attachment and the solar latitude level were in the box with the other transit. The transit offered here had the solar base/stem on it however. So I am not sure what transit originally had the solar apparatus that I have. I decided to put the solar apparatus on the other transit because I like that transit a bit better - and it has a much nicer box.

The transit offered here is in nice shape as the pictures evidence.

The box is about 80% original 20% replacement wood. It's obvious from the box that this was originally a solar transit. But the top of the box is replacement wood.

The box is covered with leather. The leather is about 3/4 present but falling apart on the one side.

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

Everything seems to work really nicely.

This instrument was probably cleaned at some prior time. I see evidence of chemical in small areas on the transit.

The optics are relatively sharp. 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.

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.
