triple track storm window screen frame parts

A home owner from Pawcatuck, CT says:
Hello,

I have a cape built in 1950, fitted with these storm windows (half screen on a double-hung window). I am missing two wndow screen frames possibly added at the time the house was resided, date unknown. (?) I see no markings from the manufacturer on these storm windows/screens. Perhaps you can help?

We  have many different parts that resemble your hardware,  but I think the best options in our inventory are the 95-015 tilt corner, 95-016 stamped corner, and 91-160 slide bolt pair. Our 91-130 pair is also worth considering.

I cannot guarantee that these parts will work for you but I think they're definitely worth looking at.
