Sash balances

Thanks for posting. I am confident we can help, but that stamp is not an identifier; it just tells us the balance's strength. Please remove the balance from the window and show us pictures of the nylon attachments at both ends. That will tell us the balance's identity. We'll do our best to help from there. 

Perfect, thanks again! Based on what I see here, you have either our S380-24 or S385-24, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
