I had a guy bring me two logs for milling and we split the lumber. He thought it was Black Walnut but it didnt have the rich dark heart wood you expect from a BW. I was thinking it might be an English Walnut. We dont see too many EW in out area but there is plenty of BW. Bark is more silver and furrows are not as deep and regularly arranged as I would expect BW to be. I'm located in Central NY.
