Let's stop right there. I don't for a moment believe that this item was made in Boston. Most everything about it: the floral four toed feet, chased foliage with "ring matted" background (see Forbes, plate 41), silversmith's center punch on the top (see fourth photo), the overall heft and construction suggest that it was made in Canton province. Can I prove it? No, not yet at any rate. Diameter, 8.5"; height .75"; weight 14.0 oz. Troy; a few minor scratches and dents but excellent overall condition.
