It is not all out of one wood. The drawer sides (and back boards on the top, seeing some of the other pics in your gallery of Gramps work) are most likely southern yellow pine. I am still going to have to stick with pecan for the drawer/cabinet door faces. There are other species that have similar color (gum which is common in the south) but the semi open face grain, porous end grain and color says pecan.
Anyone else who is more familiar with south east woods, take a crack at it.
BTW, your Grampa did some nice work. I would have liked to seen his shop. It doesn't take the newest tool the catalog is trying to shove down your throat to make something to last for many generations. Your heirlooms prove that:thumbsup:.
