Wow here’s 22 antique or vintage brass window sash locks. Actually there are 23 of the back piece that the locking part connects to. 22 of the locking side and 23 of the back side for a total of 45 pieces or 22 complete setups with an extra back. Also included are the original brass screws. Some are other tarnished or the are possibly cast iron from what I found on google. At least 6 sets look older and have much more patina. All in all a great lot. Thank you for looking 😊
