Hello,

Thanks for your post! I'm confident we can supply a replacement for this balance. Although, I will need to see a photo of the top attachment to determine the correct replacement.

The stamp tells us the weight range the balances should be able to support but it cannot be used to identify the series.

Please let me know if you have any questions.

You'll need either the S351-30 or the S390-30 to replace these balances. Our 2930 stamp will likely work in place of the 29-3 stamp. It will support a sash weighing 16 to 23lbs.

Comparison of the S351 and S390 balance shoes.
