[Fot] TR6 Dash wood?

[finishing Touch]

I'm planning on  re-laminating a TR6 dash and was wondering if anyone 
knows what wood species Triumph used on the TR6 dash. I'd like to stay 
as close to original as possible when purchasing the veneer.  In doing 
some on-line research, I've seen walnut, birch, red oak, and burl maple. 
I'm leaning towards walnut, but was hoping to be sure of the originality.

Thanks,
Mike Kurtz
