Guiseppe Luigi Casartelli (1823 - 1900) emigrated as a child from Italy to Liverpool, England, joining a relative's scientific instrument firm business. Around 1850, Casartelli produced microscopes, telescopes and other optical devices.

By the 1870s-80s, Casartelli's business focussed on supplying the heavy industries of Manchester, including fittings for steam engines, mining equipment and optical instruments for the fabric industry. One of Casartelli's sons, Joseph Henry, was made a partner of the company and the business became J. Casartelli and Son in 1896. Casartelli's business moved to 18 Brown Street, Manchester in 1922, acquired the business of another family member in Liverpool in 1929, but was liquidated during the Great Depression in 1933. Parts of the business continued under different ownerships, including the Liverpool business as'J. Casartelli & Son (Liverpool)' later'Casartelli Instruments Ltd. , in 1984, which closed in 1989, and the original business became'J.

And then'John Casartelli (M/c) Ltd. Microscope 262 is a microscope cloth counting glass, engraved with'J. CASARTELLI & SON, MANCHESTER' and'RD 14755'. The box of the instrument contains the same inscriptions.

The instrument should be dated from c. 1910 and would be used for counting threads in fabrics (the number of threads per unit of length provides evidence of a higher quality of cloth). This instrument contains a scale along which a pointer moves so that the number of threads per unit of length can be counted.

The lens is suspended above the pointer, which moves via a screw. Registered design number: 523462 (1909).

Scales divided in to: 0 - ¼ - ½ - 1 inch. And 1 - 10 mm.
