Thanks for posting. It looks like your top attachment is winged while your bottom attachment is not. Since that does not match any of our existing Series, your balance will have to be custom made. Before we begin, I just have a few questions.

Can you confirm that the length of the metal channel is 16-7/8"? Usually these balances have lengths that end on the inch. Yours should be 17". Double check and let me know.

We will also have to figure out what that bottom shoe is. Please look at the measurements for our 15-001 and 15-002 bottom shoes and note their depths. As you can see, they are 1-1/8" deep and 1" deep, respectively. Which measurement more closely resembles your own shoe?
