Another clue you gave was the impression of heavyness and being cool to the touch. Then there is the matter of all the 'gunk' in the crevices.
When I was first collecting kerisses I received a very intricate Madura hilt; it too felt heavy and cool to the touch also with lots of gunk in the crevices. I figured I would clean it up and in doing so discovered it was a casting made from some kind of heavy non natural material and aged quite professionally.

I'll be interested in what you discover when you do a bit of testing.
