Lead worker's makers marques
Three remarkable and rare small lead plaques each one featuring initials and symbols of the lead worker's trade: Water pumps, roof lines, soldering irons and dividers. Each one pierced with small pin holes where I assume they were fixed to a building acting as a trade card maybe. The lead is heavily weathered. Mid 18th C. We are still researching these items and would welcome any further information.
5.5 cm wide, 7cm high average size.
