Nice bow! Looks authentic. Those arrows look sharp too, with some scary looking tips.
The bow is black palm. It's not mahogany at all. Mahogany doesn't even grow in Suriname...back then, any exotic wood was 'mahogany'.
Those arrowshafts look really thick. As if they don't belong to the bow? Any guess on the drawweight of the bow and the spine of the arrows? I know those arrows are supposed to be too long, but judging from the tips and shaft diameter, they almost look like spears, haha!
