some websites for western antiques:

A good one run by the BBC:

Lots of bargains on eBay as well, like this one, only 250 pounds (about 500 US dollars) (I am telling you, this one is definitely a real bargain!! Their owner in Birmingham perhaps doesn’t know how much a replacement will cost. Guaranteed, not only your money back, in an proper auction this pair will get at lest 1500 – 2000 pounds, pending on their condition. ):
