These designey 1938 faucets and handles are by Italian faucet manufacturer Mamoli.
The inspiration for them came from the company's own back catalog:
"Sometimes the best ideas come from looking backwards," the company writes. "It was while leafing through an old company catalog that we rediscovered Zenith, a series designed and produced by Mamoli in 1938."
"We studied the technical drawings of the time, asking the architect Fabrizio Batoni to adapt them to current needs and we recreated the molds of this series in Deco style of which all the components are made of brass and the handles feature precious inlays with a [physical vapor deposition] finish."
