Gold engraved kinjal from ebay??

3764912314.
this auction ended yesterday and i simply forgot to log in and bid although i was planning to bid upto 1500s. it seemed like a gorgeous beauty from the pictures when i first saw it
what surprized me later, is that the price didn't go high enough compared to my estimations. When i examined the pictures and read the description later, i felt something can be wrong. Do you think are the gold engravings original?? the seller says that the scabbard is warn and loose, slides down. The leather is warn, the silver mountings are warn, niellos, paintings gone partially. There are nicks on the blade. It is clear that this item hasnt been kept wrapped in silks in a chest since its birth. It has been well carried and used. How the gold engravings on the blade stay so fresh, complete, unwarn? No break or corrosion at all, at least i cant find when i examine the pictures. What do you guys think?
