Oak block of wood (Cosham PO6)

Hi does anyone have an off cut of oak or another heavy wood not needed. The size I need is 23cm/9in in length, 8cm/3in width by 8cm/3in height. I want to make a plinth for one of my dad’s car ornaments. I have inherited it, as he has passed away unfortunately. It would be a shame just to put it in a drawer. Thank you, for reading my request.
