I have a very nice tray made for exportation (the key in the lion mark) in 1908 (date letter gothic y ) by J.M. van Kempen & sons (VK , a crescent moon and 2 dots) and assayed in 's Gravenhage (C in the helmet)





Can you tell me what this design is called ?

The reason for the post is that the tray is badely scrathed : it is a hundred years old, and it shows !



How can I try and polish it ? I heard about toothpaste ? Is that something you would try ?
Any better ideas ?
I may perhaps end up going to a silversmith and have it professionnally polished...
Thanks in advance for your answers.
