Christening mug- information

Hi all,please help with information regarding this very poor looking christening cup. Desperately needs a polish. I presume silver plated. Have been trying to identify the other marks. It stands 10cm tall. Would really like to know this cup’s ‘history’ . Thank you for any comments and keep well. I do think this is a christening cup and not a baby/child cup.Correct?

 

Yes - EPNS is for silver plated and most commonly used in the UK. The initials are for the maker, although I have no found who that is. The other marks are something unique to the maker.

 

Thank you for the comment . I have also been looking.

 

Was also thinking one part might be S&Co? First mark looks like a ‘n’

 

There's no ampersand there. S Co. Do you have it in hand and could get a closer look at the first letter?

 

I tried D, N and O as the first letter. Any other options in your view?

 

Well thanks for trying. Give it a another wipe. With the loupe it now looks like a D to me?

 

It won’t be a some sort of number right?

 

It would not be a number but I'm going to try P.

 

P - N. And I also went through all the "unknown" marks on Silver Collection. I think I am out of resources.

 

Well I really appreciate all the effort. So you are also using the site below? Seems a good site?

Also the single G mark on the bottom? Is that unusual? It wouldn’t perhaps mean German? (Just asking,been reading some info)

 

I think it's Potosi Silver Co.

That’s absolutely great! Interesting history. Many thanks for figuring this out.
