I feel excited like some forensic scientist on a trail of the great unknown.
Let us gather some facts:
* your bowl is beautifiul, certainly not some alms begging bowl but a possession of a wealthy person.
* the silversmith knew his craft, witness the nice ornament at the edge.
* the bowl, of the eastern appearance, has passed into the western domain and has been marked so in english. If only we could tell what it does say in the description of the item!
I have taken your picture again into my Nero image manipulator. I have inverted the colours, sharpened, twisted and did everything in my power in order to make it yield its secret. Rt hand english text, "Silver hand made" is not so easily discerned now but the similar text to the left
in Latin Alphabet does reveal letters K W at the end of a shortish, 5-6 letter word?
The plot thickens!
