OLD AXE ....but what type ? Tabar ?

[katana]

Acquired this axe today.....looks to be a form of fighting weapon. The handle is obviously cut down....the remaining wood is very old with some worm.
The axe head is very well made ....with two side plates (to prevent cutting the head off ??) no markings, heavily oxidised, I've removed the active rust ...to reveal a very dark stabilised rust layer.

Head has a lot of fine pitting and certainly has some age and quality. Width 5" (12.5 cms), blade edge nearly 3" (7.5 cms) Weight including remains of handle is 1 3/4 lbs (800 grammes).

I wold be very grateful for any ideas to its origin .....could this be a Tabar or similar ??

Kind Regards
David
