Hello
These are unknown brand double hung replacement window. When showing my son how to remove these I broke what I think of the shoe.
There are no stickers or identifying brands on any windows.
I took a few pics of the broken shoe and the assembly in the window. There's a metal 3 prong hook that attached the show assembly to the riser.
Can you help figure out this parts, and other parts for the entire assembly. I'm sure I'll break others.
Thank you
Jeff
