The hallmark shows that it was assayed in London in 1957 and that the maker was William Comyns & Sons Ltd (RC is the initials of Richard Comyns). I agree that it looks like a car mascot. I think that the image may be of searchlights with clouds, although I also think that they might have gone to a bit more effort to make them look cloud-like if that’s what they are. The G at the top is clearly also significant, but of what, I don’t know.

ANY IDEA OF ITS WORTH ?
