Wooden hilt cup and composite wood hilt

[adamb]

I've just noticed that the wooden hilt of another of my old Bugis keris has two patches of different-looking material (shaded areas in this schematic illustration) in more or less the same places as the other one I posted above, with lacquer over both the patches and the original wood - but this time, the repair work, if that is what it is, seems to have been much less expertly done.

Has anyone else seen this with Bugis keris hilts before?
