Hallmark help-please!!

I am trying to identify what these hallmarks stand for on this little vinaigrette that I have. I want to try and find out where it might have been made and what sort of date it might have been made? I’m not sure if the engraving on the front is significant in anyway to the marker?

Any help that anyone could offer with this would be much appreciated

Many thanks

Hello Rosie.

I can’t see your pictures very clearly but think I can make out the letters AT. If I’m correct then the maker would be Alfred Taylor. Below is an example from my own collection by Alfred Taylor assayed in Birmingham in 1856. The style and engraving of both vinaigrettes is quite typical of the era.
