Chinese Armorial Cup

This is a cup made in China in about 1760. It is superbly handpainted with an armorial in the front including initials on the right side and a cown under a crown on the left side with a large crown over both. The top rim has a nice trim as well. I looked a little if I could find this coat of arms or family crest but don't have the time to really get into it and wasn't successful. The cup displays nicely but the handle is a replacement. The top gold trim is mostly gone as well and there is an almost chip on the inside rim (it never came off and is hard to see!) The cup is 2.5 inches tall and 2.25 inches in diameter. Not marked as is the norm but there is an old collection label underneath. Please email me for more information or other pictures.
