William Ladd with Cooke telescope and electrical equipment

 In 1865 William Ladd (1815-1885) of London purchased a 4 inch telescope from Thomas Cooke together with 6 eyepieces.

Ladd brought and sold scientific instruments from 1842-1882. I am not sure if this telescope was for his own personal use or was for sale.

William Ladd experimented with electricity and from 1860 onwards electrical apparatus became a big part of his retail business.
