George James Antiques has dated this piece to the 1900s.
These are so decorative and sizeable that they would also make superb sweet dishes. Highly regarded makers, and as ever, the Chester hallmark only adds to the interest.

Of further interest; a similar pair of exactly the same dimensions and weight, but dated 1853, fetched £1200 in a Bonhams sale in 2009. We feel that this indicates the wonderful value of this particular pair.
