Unsure of date?

Firstly Hi,
Just registered as because I have turned forty I now have this desire to collect militaria, medals and silver!! I realise it’s Birmingham and could’nt find the maker anywhere but it’s the date which interests me as I have found conflicting date/letter images from hallmark sites. Any info greatly appreciated. :wink:

The date letter is the “u” of 1894 and the maker is Stainton Brothers.

Thank you very much, it’s appreciated. :smiley:
