Always nice to do one of these and find the company is still going strong, these two come from pumps made by Dawson & Downie, a Clydebank company.
The following is a potted history edited from the company’s website
http://www.ddl-ltd.com/Dawson Downie Lamont Ltd - Designs and manufactures reciprocating pumps for the oil and gas, petrochemical, marine industries. The company, Dawson Downie was originally founded in 1905 in a small facility, north of Glasgow by two families, Dawson and Downie. As manufacturers of pumps they supplied predominantly the shipyards on the river Clyde. A few years later the company moved to larger premises in Elgin Street, Clydebank where it remained in operation until 1996 when the company relocated to Glenrothes on the east coast of Scotland.
As part of the war effort the company manufactured munitions during World War I and II. In the early 1940s the company diversified into the design and manufacture of reciprocating pumps for the oil industry; a sector which now represents 90% of Dawson Downie Lamont turnover. In its heyday in the 1950s and 60s the company employed more than 300 in Clydebank and owned its own foundry.
Ownership of Dawson Downie remained within the two families until the early 1980s when it was bought by Warwick Engineering Investments. It was then amalgamated with another pump manufacturer - Thom Lamont from Paisley to form Dawson Downie Lamont Ltd. In 1985 the amalgamated company was sold to Bromsgrove Industries, now known as the BI Group. Dawson Downie Lamont became an operating company with BI Marine & Offshore Ltd and moved premises in 1996 to join its sister company Forth Tool & Valve in Glenrothes, Fife.
There is a RCAHMS record of their Elgin St works with a couple of photos, the site has now been completely cleared and houses built.
