A pivot bar similar to the 26-226 : Pivot Bar, 3-1/16" But with the first screw hole being where the first imprint hole is on the bar.
There is a number 6 or 9 imprinted on my bar

Hello from SWISCO.com. The number is the mold cavity number, and doesn't help. Since the pivot bar is diecast, you can drill a hole in the pivot bar if you need that hole to install it in the sash.
