These are an unusual and good pair of solid cast tongs
There is also a worn but attractive feather edge engraving, the bowls on this pair are shaped
more like the ones found on later "one piece" sugar tongs.
This pair l have also attributed to William Harrison, the makers mark is not all that clear but on very close inspection it appears to match his mark by the shape of the punch.
These are an attractive pair with unique shaped Bowls.
