Nittaku Combi Wood Attack > technical specifications?

[Lo_]

Hello there,
Several years ago, my coach gave me a very interesting Blade. It was a Nittaku Combi Wood Attack.
I'm wondering if you know some technical specifications about this wood. So as to compare with my current blade.

I searched on the web... i didn't find anything. Except it was an old blade, very expensive.

Thank you for you help!
