Joshua went on to patent a method for manufacturing brass tubing in 1782, the same year the firm was sold to Charles Tulley. The Tulley family ran the business through to 1844 when it was sold to Robert Mills who, in turn, sold on to Alexander Clarkson in 1873. Broadhurst became a partner in the business in 1892 but had a falling out with Clarkson resulting in the partnership splitting in 1908. Broadhurst promptly moved to 63 Farringdon Road and named the building Telescope House. In a shrewd move, Broadhurst realised the value of the good Clarkson name and began trading as Broadhurst Clarkson & Co. In house, the firm were able to produce both the lenses and the brass tubes (using Joshua Martin's patented machine). They also operated a showroom and shop on site. With the advent of the First World War in 1914, the business expanded to support the war effort, opening a second lens making facility in London supported by a telescope factory in Watford) *the previous owner has written their name just below* The brown leather caps and strap are in lovely supple condition with working buckle and secure stitching.
