Replacement part

Hello, thank you for posting,

To further review, do you have an undamaged version of the balance that we could see? We need to see a clear picture of the bottom attachment which appears to be missing. From there we can determine the Series and weight stamp option needed. Thank you! 

Thank you for the additional pictures,

With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment.

You will need a 30" balance with a 2930 stamp option. Please review and let me know if you have any additional quesitons.
