NFS - Fine Feather-Edge Sugar Tongs c.1780-95 Mrked IVB - Win a Prize!

This piece is not currently for sale, but if you can solve its mystery mark with a definitive (or at least very strong) attribution, I'll offer you your choice of either $10 off your next order, or a free coin silver spoon in good condition!

This pair of feather-edge sugar tongs are marked once inside the bow with a maker's mark that appears to be IVB conjoined, but could be MB or NB conjoined. Please click on the first photo to scroll through all the pictures. The tongs appear to be circa 1780-95, perhaps on the earlier end given the round grips. The maker's mark is clear and well struck. This piece measures about 5 1/4 inches in length, and weighs about 38 grams. It is in excellent condition. I didn't find any potential candidates among the South African silversmiths, or the Canadians, and I didn't see any definitive leads for NY or New Jersey, though NJ can be difficult. It is possible this piece is Dutch and a duty dodger - not sure! It is a very well-crafted piece, likely by a well-trained maker. Please reach out if you have a good lead!
