Help with makers mark or silver mark please.

Hi, this biscuit barrel I think is etched glass with a ?silver or silver plated rim, handle & an etched lid. The only markings are on the side of the barrel rim. It has the number D229 and what looks like a 'S' ( this may be the year date) I have looked online but cant find any relevant information. Thanks for any help.P1210970.JPGP1210972.JPGP1210974.JPGP1210971.JPG
