Small Waterskin
From WikiRaider
The Small Waterskin is a pick-up in The Last Revelation, in the level The Mastabas.
It is first used in the same level to fill the elemental scale, and later again in Temple Of Horus in combination with the Large WaterSkin for the Scales Riddle.
It can carry 3 litres when full, but it can also carry 1 or 2 litres or be empty.
