We should be able to help you with this balance, but it appears to be missing its bottom nylon fitting. This is a very important detail and we won't be able to make a recommendation without it.
Do you have an undamaged version of this same balance? If so, we can use that as a reference. I need a clear picture of the bottom nylon fitting, preferably from both a side and bottom view. Please let me know if that's possible.
Thanks! This is a huge help. Thanks for your photos. Based on what I see here, you have either our S390-28 or S351-28, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
