Interesting stuff here and we are finally getting to the nitty gritty of the English trade. Concerning the history of Cogswell & Harrison, and I quote, "Prior to the take over of William Moore & Grey in 1908, Cogswell & Harrison made some fine quality London sidelock ejectors that Moore & Grey sold under its own name"
Also, "In the post war period substantial trade work was done for Cogswell & Harrison by J. Blanch & Sons who also undertook work for companies in the Churchill, Atkin, Grant & Lang group".
