Hello, thank you for posting,

It appears you have either our Series 351, with a 15-002 bottom attachment, or Series 390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need.

You will need a 26" balance with a 2550 stamp option. Please review and let us know if you have any additional questions.
