Not sure by the photos but by the underside water marks it may be stained??. There is a book, mine is dated 1969 called 'what wood is that' with actual wood samples by Herbert L. Edlin with actual wood specimens. I scanned the wood samples maybe this will help.? If you click on the photos after the initial click on the thumbnails, they will enlarge. Grain patters may help with ID.
