Is the 2nd layer in this pic Limba or Ayous?

[Milton Table Tennis Club]

If you know there are only 2 types of wood used in this Falk W7 blade pic, Limba and Ayous, what do you think the 2nd layer is and how sure are you %?

I'm pretty sure it's ayous but I found one good source with an answer it's Limba, although they weren't sure.

I've looked everywhere including https://stervinou.net/ttbdb/compo.php without luck.

Layer 1 = Limba
Layer 2 = ?
Layer 3 = Ayous
Core = Ayous

Looks to me like maybe tong in the core
