Not sure what these sterling pieces are

[hpidaves]

These tiny bowls measure about 1-1/4" in diameter at the top. I received them together, but only one is marked sterling, along with a "3". They have some type of other metal or coating inside the bowls -- copper or gold colored. Any idea as to maker and/or piece type?

Thanks,

Hi,
Small open salt and pepper cellars with gilt interior.
Number is not relevant for identification, and if marked only with sterling we`ll never know who made them (unless exactly the same cellars are encountered bearing more marks, but even then the attribution would be questionable).

Thanks so much! Why would someone make such nice pieces and not put their mark on them?
