About ten or twelve years ago I had an order in for over two years to get two pieces of jati gembol big enough for ladrangan atasans.

EDIT

Here is an example of a different type of burl, this is thuya burl from Morocco.

EDIT 2

When this wrongko was made, back around 1990, thuya burl was very difficult to get hold of and quite expensive. I just did a quick search and found that it now is a bit easier to obtain, but still not cheap:-
