Intresting that the sellers currently listing 10 variations of Tibet sword.
To me most of the blades look real. old & laminated. {Hard to belive but they do look right, even the pitting looks genuine.}
Amazing array of modern scabbards & handels though including another one in identicle tone of buffalo horn.
Nepal is full of rusty old blades, perhaps this was a similar cache from Tibet or Bhutan etc. {or even Nepal, China India,.]
Re handled , new scabbards & straight on to ebay.
Doubt if Chinese customs would be concerned about these blades somehow, hardly Chinese heritage.
But sadley overpriced.
Spiral
ps if the blades are fake, their getting good at ageing.
