walker&hall silverplated tray

I am very new to silver, I would like to know roughly when it was made.
I have searched many silver sites but couldn’t find this mark…
please help!

53652 is the pattern number. If we compare this to the one on your teapot, which is a much lower number (1636), we can assume that it is much more recent in date, probably 1940s or 1950s onwards.

Thank you for your helpful information!
