OK, I pretty much finished the Kabuto yesterday evening.
Green paint and gauze bandage wrapping, as in the original pictures. Made from 18mm Multiplex and an old broom stick.
The pouch looks kind of odd, but actually work pretty well.
I did add a steel spike (hardened the tip) so you can stick it into the earth for a better stance, and of course so the weapon can double as a spear.
First test shots required the removal of the low/center band - the shots went low. I will fix this by changing the band dimensions so the look will be original.
