I have come across this English hallmarked sterling silver brooch in the form of a Life Buoy and with a monogram of a W under a crown. The hallmarks date this to 1918 which is why I think this could be military and there is an inscription to the back from 1919.
I cannot track down this particular symbol with the life buoy so does anyone have any ideas of what this represents - perhaps the Navy? The only similar monograms with a crown relate to the
Netherlands or the Kaiser Wilhelm but as this is British its a bit of a mystery. Can anyone help with any information please?
