Question of Spear origins

[Gavin Nugent]

The unusual form prompted me enough to add it to the spear collection.

The thrusting tip does have some similarities to Song Dynasty spear heads but that's all I have turned up thus far.

Any one aware of the origins of this spear? An ID would be appreciated.

It is 8'6", the butt is a bronze cap and that's all I know other than the tip looks slightly off centre and the patina is very old. At the tip, I see a hint of an exposed tang going in to the wood but I am uncertain if this is so or if it is just age timber looking this way.

The images are the best I can do for now.
