Persian silver wine set. The floral and bird medallion design across the belly of the pitcher as well as the central medallion of the tray is a typical Persian Qajar (Victorian) era theme. The tray is marked 84 in Persian numerals, I am not familiar with the makers mark. I couldn't find a mark on any of the other pieces, so I am assuming this was intended for domestic use.
The tray is 11" by 6.5" weighs 10.4 ounces, the pitcher is 9.5" tall by 3.5" in diameter and weighs 8 ounces, the cups are 1.75" tall by 1.6" across and weigh about 1.5 ounces each. The total weight of this set is 27.3 ounces.
