Thanks for posting. Is the metal channel, not including the end attachments, 27" long? If so, see the S380-27 or S385-27 Channel Balance. The only difference between these two balances is the 'depth' of the bottom nylon shoe. See below. Measure your old balance's shoe depth to see what matches best. Let me know if you have further questions.

Comparison of the S378, S380 and S385 balance shoes.

Thank you,
Are you able to identify the spring weight I should be using off this stamp pic?

Yes. Choose 2640 as your stamp option.
