I would need your help to identify the maker of a rather interesting set of spoons. This set is made of 3 large spoons and 4 dessert spoons. They have a simple style but their handle has some decoration on the edges and are engraved on top with a lion.
Here are the pictures of the set, and an enlargment of one spoon to show its style.




As I am not a specialist in spoons, I do not know their style name, nor I know if it is common. Could somebody tell me the name of this style and how we can designate the decoration on the edge of the handle? Was this decoration usual at that time ?
As far as hallmarks are concerned, they are legible on some spoons whereas on other they are completely worn. Nevertheless I drew some conclusions from a close examination:
- the lion passant can be seen on the 7 spoons without difficulty
- the leopard's head is legible on 3 spoons, can be guessed on 3 others and only its external shape can be recognized on the last one.
- the small letter 'a', clearly visible on 3 spoons, hardly noticeable on another one, and invisible on the 3 other spoons indicates the year 1776-7.
- the maker's marks look identical, except for one dessert spoon where it seems that the mark has been struck in the opposite way of the others. This reversed mark is very important to confirm the bottom part of the maker's mark as this bottom part is worn on all other spoons except the 3rd one. Finally it seems that the mark is composed of the script letters SH.
Here is the picture showing the 7 sets of marks, depicted in the same order used in the above photo showing the set of spoons. The 3 first sets correspond to the large spoons and are quite legible, and the next 4 sets correspond to the dessert spoons and are almost worn, but we can make out some of them:

The problem is that I was not able to identify the maker of this set. I found 2 makers with script SH mark but their mark does not fit the one of this set (Susan'h Hatfield 1739-? and Sam Herbert 1747-). Could somebody help identifying the maker ?
Do you think that my conclusion that this set is consistent, made by the same maker, at the same period is valid?
Finally, I would like to ask if somebody knows the signification of the emblem engraved at the top of the handle. I know that the lion passant is the emblem of England, but when used alone in a coat-of-arms, it designated the Duke of Guyenne. The king of England had 3 lions passant in its coat of arms. Is this emblem the symbol of some english institution instead of the symbol of a family? I apologize for my poor knowledge of these topics but I am not english at all. Here is a picture of this emblem:

It is the first set of old silver spoons that I acquired, and I wonder if it is common or not. Any opinion about this would be appreciated.
I thank you in advance for your help.
