Canadian RFC cap badge: Prototype or fantasy piece?

[zorgon]

I picked this enlisted RFC metal cap badge variant up as part of a lot from the recent Prof Charles Thomas collection auction.
It weighs 8.6 gm and measures 36mm in width. The mounting of the “CANADA” is professionally done and there is minimal gap between the two components. They are probably soldered together but there is no evidence of excess lead between the two pieces.
After cleaning, the two components appear to be of very similar material but perhaps not exactly the same.
Does anyone recognize the shape and style of the “Canada” from another cap badge or is it unique? The maximum width of this scrolled portion is 28.6 mm and maybe 1mm thick. It was indicated that it was "ex W.J. Dear" collection.
