These old Whitworth wrenches show up now and then in my neck of the woods, with their lovely Snail logo:
They were made by Thomas Smith & Sons of Saltley Ltd., Birmingham. Thomas Smith is said to have chosen the snail as his brand because his motto was, "The snail may be slow, but he gets there in the end."
The firm began in 1848 when it made velocipedes and small hand tools.
In 1896 it was operating out of Saltley Mill in Birmingham. In 1937, in addition to custom drop forgings, they advertised spanners, adjustable wrenches, hammers, and hatchets of all descriptions. In the 1959, the factory location was moved from Saltley about 10 miles east to Coleshill. Many of their products (hammers, hatchets, garden tools, spanners (chrome-vanadium & carbon steel) plus their adjustable & pipe wrenches) were exported to India. At some point the company was acquired by the Chillington Corporation, and remained on their books until at least 1992:
