Ex estate from which the owner collected small & interesting curios & collectables, no other history is known about the item and I have no way of verifying it’s authenticity. It was possibly a sweethearts brooch. The brooch / pin has English hallmarks, Birmingham with date letter i for 1883, makers mark JMB for John Millward Banks. Measures 32mm wide x 32mm high & weighs approx 7 grams. The initials of AEB are slightly crudely engraved.
