Richard et Cie (Richard & Co), Paris & London
Richard & Co started life in Paris in 1848 under a different name but then added a London branch at 24 Cannon Street in 1867 which became Richard & Co. They were mainly carriage clock makers, producing clocks in different English and French styles for the respective markets.
The London business lasted until 1881 with the Paris workshop based at Rue Bondy continuing on until the beginning of the 20th Century.
The full trademark comprises an R and C with a snake’s head in between enclosed in an oval. Other items just bearing the mark R&C probably denotes a clock sold by the company but not made by them.
