An eBay seller tells us that there was a Civil Air Guard uniform consisting of a "royal blue" sidecap and a blue denim boiler suit.
He offers the side cap (item 151001199631) with "CAP" badge, blue enamelled in a silver wreath with siler crown, and two "CAP" buttons. He also offers a flying suit arm patch (item 151001200104) in the form of the British Civil Air Ensign. Rupert Butler (talk) 14:33, 25 February 2013 (UTC)
