Chinese hilt with Tibetan blade

[Royston]

Gentlemen,

Thanks to everyone who responded to my question about the Dao. It was good to see photographs of some others.
As a new member I hope I will not bore you all with too many questions but after 30 years of collecting I have quite a few weapons that I have never really identified. Here is another. Any help with identification will be much appreciated.

This appears to have an Imperial Chinese hilt and a Tibetan blade. It looks as though it has been together a long time but having never seen another I have often wondered whether it was made up sometime in the past.
