Hi Rick. Well, i must admit i have not seen this motif used all that often in keris hilts, but Rick, the Elder (
) has shown us at least one other and where there are 2 there are probably more. I only made reference to Spirit of Wood examples to show that this motif has been accepted as a common part of Malay culture for some time so that it's use on your Madurese hilt doesn't necessarily indicate that it was made for an ethnic Chinese customer.
When i first saw the dragon i had the same impression as lordraphael. With it's bat-like wings your dragon reminds me a lot more of European style dragons. Certain, no where in Indonesia has the influence of European motifs on keris art been more evident than Madura. I could be wrong but i think it is very likely this dragon has more relation to the Dutch than the Chinese.
