Hello, thank you for posting,
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.
It appears your shoe is broken. You will need to compare to an undamaged version if possible to get an accurate measurement of the depth.
You will need a 33" balance with a 3250 stamp option. Please review and let us know if you have any additional questions!
