We have a Metal Pull Vintage Salvage item.  It measures about 3 3/8" in w x about 2 1/2" in L in the center.  The holes for the screws/nails are about 2 1/2" apart from center to center of the holes.  It has a ribbon with wheat in the center of the oval.  It does stick to a magnet so it is not brass.
