This is a broken part that Window Pro replaced in 2019. Window Pro is no longer in busness. The same part (different window) is broken now. The handyman removed it to look for a replacement, but was unable to find one. The number "8" is inscribed on the side of the coil.

Hey there. This looks like an older version of the 15-177 Pivot Shoe, which uses Series 152 Coil Balance springs. A spring stamped '8' can be replaced with the S152-8 8 pound spring. Let us know if you have further questions.
