Victorian Silver and glass table set

This beautiful set I inherited from my grandmother (1882 - 1978). It is because there are various Dutch silver marks in including an old silver mark (sword) in use from 1814 to 1905. I do not even know exactly where this set was used for. I think to put on the table for oil, vinegar and mustard. But certainly I do not know maybe you can help me?

The parts has beautiful silver nice caps with glass and the set has a silver handle to make it easy to tackle. Do you have any idea what this set was used for?
In the mustard jar is a beautiful silver spoon but I've not figured out what kind of mark it has. Maybe I still separate place on CW.
The set frame is made of wood with holes where the bottles / jars are right and four round feet.
In any case my question is; can you help me to identify the use of this set even maybe some more??
