Moline Metal Windows

Question

We need to replace the springs in the metal windows we have at an old building that was a school. The tracks are still in good shape, but the spring insert is damaged. Hopefully you can tell from the pictures what this is. I cannot find any information on the windows themselves.

I'm having a hard time identifying what you have from this picture. Can you tell me if the window is tilt or non-tilt? Can you also Show me a picture of an undamaged balance? I would also like to know the diameter and length off the outer tube. Finally, please show me a picture of the bottom of the spiral itself. If we can see that on an undamaged balance, it would be ideal.
