Stamps on Silver Rimmed Bowl?

British Silver What is it?
1

Hi, any help would be appreciated.

I have a porcelain bowl with a silver rim and I would like to know what the hallmarks are on the silver rim mean and is it plated or silver.

They read: J.G&S; with a shield shaped stamp with what looks like a man holding a bow; following that there are the numbers 550.

Thanks in anticipation.

JG&S plus an archer is the trade mark of John Grinsell & Sons of Birmingham. This is one of the marks which they put on plated items. 550 may be some sort of pattern number.
