Coldstream Guards - Pith Helmet Badge?

[leigh kitchen]

A batch of the valise stars converted from lug to "flat tube" fittings are currently on eBay as "buy it now" for £7.99, or best offer.
As is so often the case with the CG ones (including one of my two) they have a dent in the centre, presumably put there to indicate that they were cast for scrap.
(As always with ebay I have no connection to these sales).
