Lovely little badge, had to google this association as not heard of it before. Looks to go back to WW2 times but no idea when this one was actually made. Marked on the back for W O Lewis as the maker who are from Birmingham. Please take a look at the pictures and ask any Q's before bidding.
Please see my other listings as more than happy to combine postage to save costs. I send everything 48hr Tracked with Royal Mail.
