Double hung tilt window repair

A quick learner from Minnesota says:
I have recently purchased a house with a number of these windows which have the same problem. The pivot lock shoe on one side has gotten stuck at the bottom and, I assume, as a result of forcefully attempting to close the window fully, has bent the pivot pin and broken the tilt lock. I don't know the brand of window. How difficult is it to ascertain the correct replacement parts? And what caused the pivot lock shoe to get stuck in the first place?

Hello,
Take a look at the conversion video below that shows the parts we recommend for the type of balance assembly shown in your photos, which appears to be a Simonton window. I can't be sure what caused your window to jam initially but I've related a few additional videos on this page to help you through the replacement process. Thanks for posting!
