This is not the widely-known photograph of Bell taken some years later but it is taken
on the same spot, with the same anchor, and he is wearing the 'uniform' though not with epaulettes on the shoulders as shown in the famous photo. The picture probably dates to the 1850s. He is holding the Dollond brass telescope, still in the possession of one of his descendants. Bell was never in the Royal Navy and the nautical jacket he wears may have been made to his own design.
The Dollond Telescope belonging to Bell and bearing the maker's name,
and 'London', and 'Day and Night'. This instrument was in Bell's possession throughout his life.

John Dollond FRS (10 June 1706 – 30 November 1761) was an English optician, known for his successful optics business and his patenting and commercialization of achromatic doublets (for telescoeps). In 1752 he joined his eldest son, Peter Dollond (1730–1820), who in 1750 had started in business as a maker of optical instruments; this business is now Dollond and Aitchison. His reputation grew rapidly, and in 1761 he was appointed optician to the king.
