Sterling silver child's cup in Boston Colonial form with strap handle, and hand  engraved on the body "James Constable Mc Gusty" in block letters.  The cup weighs 5.6 troy oz. and measures 3 1/8 inches high and 3 1/4 inches high to top of handle and 2 7/8 inches in diameter at the opening.  Marked on the base "Tiffany & Co.  19184 Makers 1852  Sterling Silver. 925/1000 M." and "Original in the Clearwater Collection Metropolitan Museum of Art" and "Reproduction Original by John Dixwell  Boston 1680 - 1725".  There's some rippling and tarnish at the base rim, and several tiny nicks on both the foot and the mouth rims, and one slightly out-of-round area on the lip to the right of the handle, otherwise in good solid vintage condition.
