Refracting Telescope

Description
The American military began using telescopes with stable mounts and tubes of fixed length in the 1890s, to supplement the spyglasses it had used since the Revolution and the field glasses (binoculars) it had used since the Civil War. This example is of that sort. It is 5 feet long, with a wooden tripod and heavy cast-iron mount. The objective (missing in this example) would have been 3 inches aperture
This came to the Smithsonian from the U.S. War Department. The lenses are lacking.
