Awning windows in need of parts

Hi there,

I have a newly updated house that has old windows. Some are not working at all and need replacement parts. The cranks are easy enough to replace but what is broken on most of them is the bottom window of 3 panes. It seems like the mechanism that would "lock' the window or hold the window tight is missing or broken. I could not find a brand name unfortunately, but the house was built in 1965 in Florida.
