Crowns on Aceh weapons revisited

[Loedjoe]

Here is another siwaih - not quite up to the high standard of many of the others shown in this thread.
Black wood hilt with highlights of reddish brown (ebony?), black wood sheath with dugong ivory tip and ivory projection. 42 cm, blade 27 cm (9 mm thick at the base), hilt 10.5 cm. A band presumably missing an inch or so below the top of the sheath.
