Can you identify what balance this code refers to?

Hello,

We'd be happy to look into this for you but we'll need to see photos of your balance removed from the window since the stamp code only indicates the spring strength. If you could show us the connecting point between the spring and pulley inside the metal channel, both end fittings, and the pulley clip, that would help us confirm if our stock balances could work for your repair or if they would need to be special ordered. Thank you!

Thank you for the additional images! 

With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment.

You will need to measure an undamaged bottom shoe from another balance if possible to confirm an accurate measurement. 

The length of the metal channel excluding the nylon attachments should measure 27" long and you will need a 2640 stamp option. Please review and let us know if you have any additional questions!
