One piece of hardwood (Risinghurst OX3)

I would like to repair our garden table and am in need of 1 length of hardwood that I can cut into 4 brackets.
Dimensions roughly: 1 piece of L 500mm W 60 mm x T 20 mm. If you have an offcut of knot free material that you are able to spare, I would be very grateful. Thank you, Gita
