Hi Guys, picked this one up yesterday.
The RAF Pilots wing in the form of the sweetheart broach is perhaps one of the most common designs of sweetheart of the war. They can be found in various qualities depending on how much one wanted to spend. They can be found in solid gold, solid silver, sometimes with coloured enamells or in plain white metal.
This example is one of the later, with a chrome plate finish with a slightly contrasting white metal "RAF" in the centre.
