Drawer bottom is pine, no doubt about that, back of piece appears to be beaded tongue & groove construction,
Jacon4, my eyes must be gettin bad
..... cause I can't see a drawer bottom, pine or otherwise.
But I agree with you on the date because of those “tear-drop” pulls, the mortise on the drop-down front/writing surface and the 2-wheeled casters.
And I see only 2 knots, one in the beaded tongue & groove board in the inside back panel and 1 on the side panel and it is “tight” grained and from an extremely large limb.
And the more I look at it …. the more I think it is stained Poplar ….. because of the “panels” in the drop-down front. They are “dark” on the front and “light” on the writing surface side.
Virgin Yellow Poplar, also known as Tuliptree, were humongous trees that made for extremely wide, strong, knot-free lumber for furniture making.
Now Basswood, also called Linden, was also a large tree that made for extremely wide, strong, light in weight, knot-free lumber for furniture making, but, it is extremely “white” in color compared to the yellow Poplar.
