Alan,
Perhaps I erred by not being more specific and saying that the very earliest forebearers of the keris may have originated in India, and not the "modern" keris form. I am fully aware that some Indonesian scholars even argue this point.
As you know I am an admirer of your research and knowledge, and I have ascertained the same sort of generality in your own work in introducing the origins of the keris and the early influence of Indian seafaring traders in Indonesian history:

So that is, indeed, what I meant and apologize for the lack of specifics.
