The use of the various marks may have overlapped hence the uncertainty. The first two marks are much more common than the third. Its use may have been cut short by the requirement to show the country of manufacture. A good way to firm up on the dates for these earlier marks would be from jugs with hall marked silver rims. Unfortunately these are usually too worn to make out the date letter.
The last three marks have also been seen occasionally. The upper left and right on 1 pint (brown sprigs) and the lower left on 2 and 3 pint (white sprigs).
