I have one the same!!, Forelimbs are definitely Beech, Rear part is deffo walnut!!
The beech part is on the left of this mk1 stock that I had to glue and dowel!!, Rearpart is the walnut bit at the right..
And the rather pretty one I bought from B'rider
By the way- I'm pretty sure the Sile one piece stocks were beech too
