Dear Friends,
I ask your help to identify the source of this tablespoon sugar cubes or strainer in silver long cm.15.
The fund has the punches of a lion and then on the handle of a head and others who do not understand vulnerability.
I add 4 images
thanks to those who will help me

Silver sugar casting spoon

Hi, not British but Dutch,the lion walking the right way. Dutch 2nd standard mark silver 833/000 fineness. Minerva head, assay office mark with the regional assay office letter A for Amsterdam and the year letter script T for 1828.
For more information about Dutch (hall)marks see:

I believe the maker's mark, although partly rubbed to read: IV over W with clover mark for: Jacob van Wijk Sr., registered in Amsterdam 1819/1846
Below an other example of his mark:



Best,
