Stamped no. 320bs1

I'm confident that we can help you with this balance, but before I recommend anything I'll need a couple more data points.

To start, can you show me a photo of the pivot shoe that connects to the bottom end of the balance? Can you also tell me that shoe's width?

I'll also need you to verify the length of the metal channel. It should be either 32" or 33", based on your stamp.

Lastly, please weigh the sash on a scale and tell me its precise weight, down to the ounce.
