I bought this lumber from a local sawyer about 2 years ago and he said it was QS RO. I was so dirty that I was not able to tell what it looked like, but after I planed it, I knew it was not RO. I like it and would like to know if anyone knows what it is. It is the darker of the 2 boards in the photo. It looks like it has some spalting. The lighter one is QS RO.
