looks old. but from what ive been learning. there are quite a few deliberate fakes with old oriental vases. for 18$ its worth it to take the risk lol. I would have bought it aswell. I would take those photos and contact an oriental art dealer. perhaps a few . good luck man!
They will be able to tell you. There were a lot of reproductions made in the late 1800s to early 1900s for the tourist/export market. Chinese market is so hot right now that even the reproductions are worth money.
