I took this sword to a military sword buff and he said it is 100% Indian manufacture just a copy hilt. it also appears that the grip is not wood or leather as on the British swords. What ever it is it is hard and in parts there seems to be something like a grain structure. Could it be stained ivory? That seems rather extravagant but in the late 19th early 20th cent it was used with gay abandon. I am not sure if it is safe to speak like that these days
. I dare not clean a section to look see.
