18thC fiddlethread tongs by Beriah Chittenden, c1790
When these tongs were made, Chittenden was working in New Haven. The tongs have cast extensions on the fiddlethread arms, ending in shell nips (see pic); there is a feathered script mono A T R on the bend. Length of the tongs is 5-3/4". Condition throughout is excellent. Mark is B C, struck on both arms. It may be found in Hammerslough's tome on Connecticut silver.
