Susan Polar shows the set that is supposed to be identical, that the museum bought to display, http://susanpolgar.blogspot.com/. The photo is unfortunately distant. The set looks closes to a John Calvert set from the period. It does not look like a John Barleycorn, a St. George or an Old Divan Cigar Store set, which were all also popular in England.
You can see a replica of a similar ivory John Calvert set at http://www.houseofstaunton.com/netwebpics/calvertfauxivory-1f.jpg. The House of Staunton is making it in faux ivory and selling it for $129.
