Help to ID Balance

Question

Hello!
When you have a minute please help me to ID this type of balance. I'm interested in any info you might be able to give - it doesn't look like any balance I'm familiar with. Looks like an aluminum cover, the sash is wood, and the owner says the windows are about 10 years old. Double hung, non-tilt. I'm interested in how to take this window apart to replace the balances. Also any general info on manufacturer etc. would also be awesome.
Thank you!

Many thanks for writing in. These wood sashes uses vinyl sash jamb liners. You need to tilt in the sashes and remove them from the jamb liners. Now you can remove the jamb liners from the window frame. Laying down the jamb liners you can slide out the ribbed balance from the jamb liner and show us. We will need to see the locking shoe connected to the cord, the length of the metal channel balance and the spring weight stamped on the channel.
