Need help what to order

Thank you for reaching out to us. We can help, but we'll need more information to ID this balance. Can you upload photos of the top fitting? We would also like to see an image of the inside of the balance’s metal channel, where the innerspring connects to the pulley mechanism; this connection is located in the middle of the channel.

Additionally, we'd like you to measure the bottom shoe as shown below.
