Peachtree balance question

A home owner from Oviedo, FL says:
Hello,
I have a number of Peachtree windows of different sizes. All of my balances are broken. In the one I took apart, it has the number 2518 stamped on it, but that does't match any of your balances. It is just over 26" long and just over 1/2" wide. Appreciate any help you could offer. Thanks!

Thanks for contacting us. "2518" isn't a product code or anything, that just indicates the calibration of the spring. That's probably why you couldn't match it up.

The only way to find a matching balance is to go by physical details. However, the balance you show in your photos is damaged, so that won't be possible. We'll need to see clear photos of an undamaged version of this balance in order to find the best match. We would especially need to the the top, bottom, and whatever hook, clip, or shoe is at the end of the cord.
