Hi I wonder if anyone help? I have a sweetheart badge which has rifle and union jack on it. Its marked . 375 ( 9ct gold) and a series of other markings- HWL and a rounded capital Q in a box along with other markings. Can anyone advise about these other markings, an confirm is this is Chester assay mark or have any information on dating/period of this badge?
Any help would be most appreciated.
