new here - no pic as yet, need help !

Hi there,
just joined this site. very helpful and informative.
Not yet mastered doing pic of item, and im not very computer minded !

Need bit info. as follows :-

Have a glass sugar shaker, or some shaker with silver top and seems like 3 hallmarks or something.

looks like a small halfmoon/teardrop shape mark, then has think a Q S and a number 25 …
sorry its vague, no idea what it is ?

any ideas? was told it could be a hallmark not from UK ?

I await. regards, best wishes.
