Pair of vintage old architectural salvage bathroom lavatory sink or tub faucets with porcelain buttons. They are marked "Atlas" with porcelain Hot / Cold medallions. These measure about 3 1/2" above the mounting surface. The threaded nipples are about 3/4" OD and 2 1/2" long.
These have wear to the plating with a lovely patina of age. The cold one is showing about 50% brass.
