During the war, thousands of businesses ran their own ARP teams. Many provided badges to their employees to denote their service within the company's ARP teams. Actually seeing the badges being worn is rare but below shows a gentleman wearing his. The badge may be for the Neath Steel Sheet Galvanising Co. Ltd.
If you're interested in ARP badges and other Home Front badges, buy yourself a copy of Jon Mills' "Doing Their Bit: Home Front Lapel Badges, 1939-1945".
