When my mother married my stepfather they bought a small bungalow, similar to this one.

It was an Aladdin Readi-cut mail order home that came precut and was assembled like a conventional stick built home.
The kitchen had a wall hung white porcelain sink with three faucets. Hot, cold, cistern. The cistern was a copper lined wooden tank in the attic that collected rainwater from the roof and gravity fed to the kitchen sink.
The tank had been stripped and sold for scrap by the time we came along and the faucet had been disconnected but not removed.
