Broken Sash bar/pivot pin - double hung window

A handy person from Framingham says:
Attached pixx of unbroken sash bar. Cannot find the window manufacturer. I believe the bar is part of an assembly and attached to plastic piece that gets inserted into corner. Can you please try to help me figure out a replacement part ?

Hi, Tony. This funky-looking thing is probably the distinctive Harvey pivot bar. Look at the two we carry, the 26-164 and the 26-416, and see which one is the size you need.
