Beautiful pair of mirrored wall lights with Murano glas arms, Piedmont 18th century

This pair of wall lights comes from a piedmontese villa, where it had been placed all the time. They are part of a series of four pairs. If one is interested in the whole series, please ask me for pictures of the other pairs. The mercury mirrors have a gold border and original murano arms. The arm attachment is of bronze. Piedmont circa 1730
