A hands-on inspection would be necessary to check if the vase was overpainted/repainted. Even if the body could be 19th century, the colors, especially the gilt may not be that old. I would expect at least some wear of the gilt decoration. This type of red was most common in the late Qing dynasty and early republic, I think.
