Keith Page 48 of British Glass 1800-1914, Charles Hajdamach. , shows two jugs. The left hand one has a very large matted flower and leaf design on it. Looks remarkably similar to the way your leaves are done, but maybe a variant in design pattern? The handle is different to yours. CH says the twisted handle on that jug was a registered Richardson design from the early 1850s.
The difference I can see is that that one has a twisted handle (much more difficult to apply?) and also the star cut base is more intricate, many more radials.
