Read the description of the  Powell & Lealand No. 1 in Carpenter, The Microscope and its Revelations, Dallinger Edition (8th) 1901.

This instrument represents the final version of the Powell & Lealand No.1 which was in production for more than 60 years. The stage of the microscope is marked: Sold by, C. Baker, Optician, 244 High Holborn, London. According to B. Bracegirdle in Notes on Modern Microscope Manufacturers,  Powell and Lealand ceased the manufacture of microscopes in 1901. In 1904, Charles Perry (the P&L foreman) began working in the factory of C. Baker where he continued to make instruments to be approved by Thomas Powell until 1914.
