This common-style drawer pull probably comes from out of the 1930s or 1940s. It is the basic tear-drop pull backed by a simple round back plate. The tear drop on this pull is heavy, stout cast iron that hangs from a thick brass post.
The tear drop measures 1 3/4 inches long and 3/4 inch wide. The brass back plate measures 1 3/4 inches round. It has a small hole at its base for a brad or screw in order to prevent the plate from swiveling. The post fits snugly into the back plate and extends a 1/4 inch beyond the back. It is pushed into the drawer and then a screw is inserted from the back to thread into the post.
The total drop from the top of the plate to the bottom of the tear drop is 2 3/4 inches. A screw will be included.
