I'm looking to order 4 of the above parts for my Hayfield H201 window. They where manufactured in 2004. I believe this is called a quick tilt mechanism. They normally will slide up with the window and hold it in the up position.

Your pivot shoe looks like our 15-111 that uses 1/2" wide Series 160 coil springs. Look over our dimensions and see if this matches your original hardware.
