Hi, don't know the name of the window but 31 years old. Need a few of the steel bars on the bottom of the operating sash that allow the window to seat in the spiral lifting mechanism. And maybe the clips that hold the top of the moving sash in place. There is a number in the glass but maybe just a glass manufacturer. Would love to be pointed to parts for this window as I have 15 of them.
Thank you kindly for this.
Bill
