We cant seem to figure out exactly what we have. The markings on the balances are confusing.

Thanks for posting. This balance looks like our S380-27. Check it out and see if you agree. Make sure the nylon attachments on either end are the same as your own. I can't quite make out your bottom shoe, so take special note of that.
