The excellent archive at the website of the
Edinburgh Incorporation of Goldsmiths shows several different Lawson & Co marks and describes them as Wholesale Jewellers & Importers. Lawson & Co are mentioned in Glasgow Assay Office records between 1903 and 1934 although they may have been producing silver as early as 1891.
Lawson & Co are listed as Wholesale Jewellers in an 1896 telephone directory at 85 Buchanan Street, Glasgow. They were at the same address until at least 1957, but by 1968 had moved to 59 Bath Street, Glasgow, lised as Lawson & Co Ltd, jewellers & silversmiths. In 1978 they had moved to 80 Buchanan Street, listed as Lawson & Co Ltd, jewellers.
