Can you identify the model number of this window I am trying to find parts for, the lock and the lower right hand corner of the glass say Alcoa?
The window measures 22 wide x 57 tall, they are tilt out style?
Thanks


This is my second set of pictures
This is additional pictures of the windows I am trying to ID.
The locks and the glass both have the name Alcoa written on them, the windows are white vinyl, and fold outs to clean.
On both sides of the windows in the channel section they have a white plastic tubing that is old and breaking to the touch, it appears inside the white tubing is a metal spiral tube?
Some of the windows when raised do not stay up very well, like there is a spring broke inside?
Thanks
