Tilt In Window Coil Balance

A quick learner from Appleton Wisconsin says:
Looking for a possible replacement Coil Balance for the one shown.
Dimensions are approx. 1.25" X 9/16"
"4" is imprinted in each coil.
The first picture is from the bottom of the sash from a same sized window showing the basic window information.
Any help would be appreciated.
Thank you!

Hello,

Your photos appear to match the 15-180 balance shoe, which is compatible with the S190 coil springs. Take a look at the products specifications to confirm. Thanks for posting!
