This photo was taken at Christmas in 1944 and shows the owner of a toy shop who would donate gifts to children in the Paddington area of London. The post warden (going by the star above chevrons) has five war service chevrons on his sleeve so was in the service very early on. He also has a badge on his right breast pocket that was new to me. It appears to be a FIRST AID badge for the LCC (London County Council). I have tried searching for this online but as yet have no come across this variety. Would be interesting to know the colours of the badge.
Photo was kindly sent to me by Chris Ransted.
