Is it universal, the saying that a suspected mistruth is a 'furphy' I wonder?
Well here's a Furphy for you, trust me, it says so on the sides of. I'd never seen one before, until I went out west recently.
These carts were used in military camps during WWI for water storage. An invention by John Furphy and first made in the 1880's. You can read further information here on the famous Furphy water cart.
