Hi,
Welcome to the Forum.
An amazing plate, and you say you have 'some'!
The 'some' is good news, for unfortunately none of the marks you have shown relates to the maker.
See:
http://www.925-1000.com/british_marks.htmlThe first mark, the Lion Passant, indicates the Sterling standard 925/1000.
The second is the Crowned Leopard indicating that your plate was assayed at London.
The third is the date letter that would appear to be for 1726.
Hopefully some of the others will show a maker's mark. It would be good if you could post photo's of the other sets of marks so that we can be sure of the date.
Trev.
