Telescope

Description:

Brass telescope with a 3.5 inch achromatic objective, three eyepieces, finder, two telescoping braces, handles for movement in altitude and azimuth, and a pillar-and-tripod stand. The tube is 39.5 inches long. The “TROUGHTON LONDON” inscription on the faceplate is that of Edward Troughton, a noted optical and mathematical instrument maker who began working on his own in 1805. Troughton took a partner in 1824 and began trading as Troughton & Simms.

The telescope fits into a mahogany case with brass hardware. The attached shipping labels refer to Dr. W. H. Fishburn, Dr. Henry Van Bergen, and J. C. Leeds.
