Interesting info on J. Blanch & Sons, "In the post war period substantial work was done for Cogswell & Harrison by J. Blanch & Sons who also undertook work for companies in the Churchill, Atkin Grant & Lang group. At one stage Blanch actually operated from Cogswell & Harrison's Lots Road premises. However, we have this also, "During this period, Blanch purchased guns 'in the white' from Cogswell & Harrison."

So, exactly who is building who?
