antique ornate arts and crafts doorknob plates

Lot of four old, Eastlake vintage, ornate architectural salvage, door knob escutcheon hardware plates. These are stamped steel. Great for a restoration project! They measure about 5 1/2" long and 2 3/4" wide. The socket for the doorknob is about 5/8" across. These have some rust and discoloration and one is slightly bent.
