Thanks Nathaniel,
I will know more on the length of the head when in hand some time away.
There is so little info on spears in general unless they're African, that I find unusual versions very interesting and the numbers at home are growing.
I do not think this is Chinese at all, just noting similar shaping to the head. The bronze butt is similar to Moro profiles but the large dome centre at the very end I can not recall seeing nor does the tip form fit Moro regions to my eyes.
Note too the thicker base area and tapering to the head, this too may indicate region
