Thank you for your comments:-
Diane & Tony,Thank you it is a good example of the rippled grain in ash not seen very often in fact I didn't know it was there until I started turning it
Les,It seems you now have the answer to your species of wood.
David,Thank you for your pictures.
Explanation I found on Rippled Ash:-
This unusual rippled characteristic is normally found in old park trees which have sufficient space to grow in
girth rather than in height.An even mass of ripple figure running at right angles to the grain is combined with a series of grey/brown streaks with a
straw background with the grain this produces a 3D effect.
