Am I correct ?

Have identified these tea spoons as Glasgow , 1855 sterling silver , but not sure about makers marks . Am i correct in my assumption?

Last one I am sure is plate but cannot find details ? Any help appreciated ,

Cheers , Pete

The Glasgow date mark looks like 1852 to me.
The WA mark could be that of W. Allen, he was working at that time.

The silverplate mark was used by William Page & Co., Birmingham, England.

Thanks , yes 1852 looks correct .
