K31 (new to me)

Looking to buy my first K31.
Wondering if its walnut or some other wood?
Here is a pic.

The K31, the early ones had only walnut stocks. Later models has the birch wood too.

Beech stocks came when the war dried up the supply of walnut.
Congtats! Nice rifle.

Latigo

looks walnut to me.
