Pivot Bar Set, Harvey

i am trying to replace a sash pivot for my older vinyl window. on the pivot it has some writing. pat pend. 1523 1478 and a large R with 1888 next to it. this pivot is a right angle with a small square pivot sticking out of it. two holes on the bottom and one hole on the side of the sash. ...

The pivot bars and cams have completely corroded, fused, and broken on several of my older Harvey windows. Amy help replacing the parts would be greatly appreciated. Thanks.

I need two pair of (left and right) sash piviots (like the one in the photo) for the lower sash on older Harvey DH windows. Windows are probably about 20 years old or older.

I need to order a few of these!
