A Madura Keris?

[A. G. Maisey]

35 years takes us back to 1985, I'd guess that dating is possible.

The Boys from Madura didn't really get up & running until about the mid 1980's, and my recollection tells me that this sort of very well carved blade did not start to appear until around the early 1990's.

But I guess anything is possible.

In any case, no matter when it was made, its pretty nice work.
