Antique Door Knob

Purchased from an antique store and ended up not using. In good condition. It does not include the screws as I didn't receive them when I purchased. Please review photos as to what is included. The two black plates are not original to piece. There is some wear/scratching to both knobs, please let me know if you have any questions. Entire unit is roughly 5.5" in length, each knob is roughly 2.5" across.
