Thank you Gav and Wouter for the quick replies

. A quick search using the information you provided, helped me find some examples in an ethnographic collection

I would like to believe this is quite old, certainly has a hard, glossy patina but not certain as to the colour changes as Palm wood ages.
Kind Regards
David
Pictures below. The blunt ended one is New Guinea (purchased 1891-1893), the one with carved designs is also from N.G the plainer, pointed one is attributed to the Torres Strait.
