I am looking for some information on where I can find replacements for some hardware. I have old windows and each window has what I like to call a pivoting wedge that holds it open. There is no counterweight or springs that help. I have a few that are broken, a few that I have to use shims of paper to help, and a few that are just gone. I do not like having to use sticks to hold the window open and I have not been able to find any kind of replacement anywhere. If someone has an idea of replacement hardware or even the name of the device I would be most grateful. I can not afford to replace the windows and I will be painting them soon and would love to replace these with new ones or even an alternative option.
I have attached a picture at the end to help.
