Samuel Plimsoll, MP, is remembered for his safe load waterline mark, introduced to prevent unscrupulous shipping owners from overloading their ships and so taking excessive risks with the lives of their crews. It is now found on all commercial ships worldwide.
Handsomely etched with his image and the Plimsoll line, in this case used to mark the "safe load" for a generous helping of spirit.
Capacity to line is 220ml.
(Sorry, whisky not included!).
