Hi Jim,

The coil balance assembly you have here reminds me of the Series 140 Quick-Tilt Balance. To determine if this will be a fit in your windows, take a look over the dimensions.

The stamps on the coils indicate the amount of tension the springs on the assemblies hold. I've tagged the corresponding coil balances for the stamps you've confirmed below. Be sure to double check the stamps on each of your springs.

The dimensions are correct. I don't see how the coil is mounted to the window frame.

Okay, prefect! The coil housing on the assembly has an installation hole, like the 14lb coil in your photo. The dual coils on have one installation hole as well.
