LOL, yep, its pinned. Wood Pins are used in mortise & tendon type construction where they drive in the pin to hold the rail/apron tight to the stile/leg of tables, chests, chairs, etc. Here is a pic for Hosman, Sheraton single drawer work stand, curly maple, about 1830-40, New York. Notice the curved front of drawer? The guy who built this stand saw the comming late classical/pillar & scroll style comming and decided to incorporate it into this sheraton stand. Well dang, cant see curved drawer front very well in this pic but its there, trust me, lol
