"Pair Of Burettes, Spain 1680-1730, Sterling Silver, Silversmith Rosa, Pair Of Bulbs"
Extremely rare pair of cruets from the 1680-1730 period, very probably Spanish. They are very heavy, as is often the case with the Iberian production of this period. The lids are topped with an A (Aqua) and a V (vinum). One of the two lids was later redone as shown in the photo. Weight 370 grams per pair.
