Thanks for reaching out to us! There is a chance we can supply you with a replacement for the balances you need but I'll need to see a photo of an undamaged balance, removed from the window, to identify the correct replacements. I am specifically looking to see any attachments on the top or bottom of the balance.

Unfortunately, the stamp cannot be used to identify the series you need. It is only used to indicate the weight range the balance should be able to hold to support the sash weight.

Please feel free to reach out with any other questions you might have in the meantime.
