I was able to obtain some large blocks of wood. There are three blocks I cannot identify. I have attached 2 pictures of each. They are quite heavy. The wood in pictures wood 1 and 2 calculates to about 50# per cubit foot. The wood in pictures wood 4 and 5 calculates to about 61# per cubit foot. The wood in pictures wood 3 and 6 calculates to about 73# per cubit foot. I was hoping that with the pictures and the weight someone with a lot more experience than me can identify them.
