Thank you for posting, and for the pictures. Unfortunately, your bottom shoe in the picture on the right appears to be broken, and I won't be able to identify your balance Series without knowing what it is. If at all possible, can you upload a picture of the bottom attachment in your other balance?

Also, can you please take a picture of the number stamped on your balance?

Thank you for the picture. We just need to know a bit more information. Please refer to the following chart and compare the width of your bottom shoe to the width of the shoes shown in the examples. Does it have wings? Is it 1", or over?

The bottom guide has wings and is 1" wide (15-005)

Thank you. Please take a look at our S380-29 channel balance with a 2860 stamp option. I believe that this will work for you.
