Antique Reticulated Grainger Worcester China Porcelain Vase c1875

Great piece with great pierced and gilt decorations. Dates to 19th century and is in excellent original condition. No chips, cracks or repairs. For being about 150 years old and with this fine a reticulated pattern it is amazing to be this clean. Measures about 4 1/8" tall and 2 7/8" diameter. Is marked on base as shown. I have reduced this about 40%.....I have no where left to go and If anyone has any ideas why it is still here....please enlighten me?
