fair price for jarrah - old woodworker don't want to rip him off
I hope someone can help me. I have come across an old woodworker in the hills of Perth who has a some jarrah his family are trying to sell for him. I am very interested in some jarrah he has which is old wood from a train yard, not the best and not the worst, that is 4000mm x 245mm x 45 mm (also has some 6000mm). He does not know what it is worth and nor do I. I want to offer him a fair price as I don't want to take advantage of anyone. What is a reasonable offer to make that is fair for both of us?
Thanks in advance.
