Jugs of this type are usually called 'beer jugs', but it seems infinitely more likely that they were used for wine; beer was the drink of the poor and the young, in an age when water could be dangerously infected. Further, such jugs usually hold about the same capacity as decanters - somewhere between a bottle and a litre.
Typically wine jugs of this type were made in the 18th century until c.1775 when glass decanters took their place. Many have no lid, but some, especially later ones do, just as decanters have stoppers.
This jugs is of standard, baluster form with a hollow handle and pouring lip. It has no armorial, crest or monogram engraving and it appears it never has had, as there is no 'thin spot'. The patination is good and even all over. It bears the mark of Thomas Wallis, a well respected London silversmith in 1769, but close examination reveals that his mark is over-striking another. This was a quite common practice in the 18th century. The hallmarks and that of the maker are clear and well struck and there are the usual maker's and sterling standard marks in the lid.
It is in excellent condition and is highly fit for purpose.
