Chestnut Wood

A visit from a homeowner with some pieces of old lumber from a barn he is renovating. Is the wood chestnut?

Some was and some wasn't. Chestnut was a common building material before the blight hit but so was oak. The two woods can be pretty easily distinguished by looking for the broad rays that are present in oak but absent in chestnut.
