On offer is this extremely rare, pair of antique French. The base has the convex design – this one being the’flaming grenade’ (associated with the sapeurs-pompiers/firemen) and the words’École Speciale Militaire’ – whilst the top has the convex (opposite to the base). Used to make buttons, the material (brass, copper, silver etc) would be left with a repousse version of the design. When in place exactly, they sit together perfectly. Nice and unusual decorative item / paperweight etc. Total height of 8.3cm. Raw unpackaged weight of 450g, will be over 500g safely posted. In excellent antique condition.
