Single hung balance

The stamp from the balance will tells us the weight range the balance may be able to support but it cannot be used to identify the series, unfortunately. I'll need to see photos of the top and bottom attachments to determine the correct replacement for your balances.

Please let me know if you have any questions in the meantime.

Thanks for the additional photos. This balance is a match for either the S380-28 or the S385-28. You'll need to measure the depth of the shoe to determine the correct replacement match.

The 2730 stamp will support a sash weighing 13 to 19lbs.
