Here we have a rare little late 18c early 19c silver gilt vinaigrette . The piece is solid silver bears the makers marks to the underside. 
i'm afraid I don't know the maker, but i'm lead to believe it is dutch. The piece even has its original sponge which is a lovely little touch. 

It's in nice original condition,  The gilding is a little rubbed, but it has a great warm patina. I haven't polished it, but please take a good look at the images to assure yourself of condition. 

Thanks for looking and good luck
