WW2 Deputy Fire Guard Officer Printed Shoulder Title Badge

The below Deputy Fire Guard Officer shoulder title badge cropped up on eBay and sold for £46. I'd not seen this particular shoulder title before and is has quite a unit shape. The rank was the second highest in the Fire Guard organisation (one below Fire Guard Officer (badge was square) and above Assistant Fire Guard Officer (badge was oval). Personnel holding this rank wore a white helmet with one broad band below one narrow band.
