Have a look at these which just fell into my hands being in with some navy buttons and described as such, knew i'd seen the wheeled badge on here somewhere. As you can see there is an embroidered blue and gold badge with the same symbols and a five sided star, rank badge? The large buttons were for the greatcoat? Would four have been enough? There are six smaller buttons which seem slightly under the size of regular tunic buttons, would they have been smaller because it was a female service? And lastly the last lot of 2 badges and buttons sold on ebay in Aug 2011 for £98 so your boss has a good eye Ade.
