I'm looking for a replacement balance for an anderson double hung window, circa 1975.
The attached picture shows the only identifiable markings on the balance.
Please help!

Thank you for your patience in this matter. We are having a bit of trouble identifying what this is, exactly. The crucial stamp appears to be obscured in this image. Could you tell me what the number is next to the P? Is it a 6? If you can't read it either, maybe check the other balance in the window.

If it is a 6, check out our 24-637. This can replace balance boxes with the stamp 6P 23.
