Dreweatts, Donnington Priory, 2019-12-11, lot. 300. Ben Brown of Dreweatts (12.9.19): The only detail we are able to provide is that it is being offered on behalf of an antique dealer based in Sussex, England at our recommended auction estimate. Furthermore, current vendor has owned the item for approximately the past 10 to 15 years but cannot recall any further detail than this, other than it was probably purchased from another auction room in England. Unfortunately there is no further detail to the provenance than this.
