-Antique Brass and Leather Three Draw Telescope Made By T Underhill In 1848

This beautifully engineered scientific instrument is an Antique Brass and Leather Three Draw Telescope Made By T Underhill In 1848. It is being sold as a collectible for display only due to the age of its optics.

brass inbuilt sliding cover to eyepiece.

In pretty good condition for its age, there are a few scuffs and blemishes and a small dent in the lens cap. Moving a tiny slide mechanism on the eye piece reveals a brass inbuilt cover, which is a little dusty.

I haven't attempted to polish it as some people prefer to see the original patina. You can see through the telescope but I find the image a little blurry and, as you'd expect with antique optics, totally distorted if you try and focus through a window. 

Approximate Size:

• Maximum Diameter: 4cm
• Length when retracted: 21.7 cm (~ 8.5")
• Length when extended:- 53.4cm (21")

Comprising three brass sections, and covered with brown leather,  the top section is engraved 

T Underhill, 4 Old Millgate, Manchester

According to the Directory of British scientific instrument makers, 1550-1851, page 285 (appended):

Thomas Underhill was an optician who worked at the following addresses in Manchester: 40 Water St (1834–1838), 70 Bridge St, Deansgate (1841), 4 Old Millgate (1848), 2 Corporation St (1858–1864), 4 Corporation St (1868), and 53 Princess St (1873–1881).

A lovely old telescope that would take pride of place in a room or collection.
