A three draw brass telescope signed near the eye-piece,'Elliott Bros, 449 Strand, London'. It measures 30" long when fully open and 10.25" when closed. It has a triple element main lens of 2.2 diameter. The engraver has made a small mistake by cutting a 4 and a 7 on top of each other. The company worked at 449 Strand between 1876 - 1890.
The pattern became the standard spotting'scope' for the British army for half a century.
