Thanks for posting. This looks a lot like our Series 390 channel balance, but can you confirm the length of the metal channel? A stamp of 3130 usually indicates a metal channel length of 32". If it is 29" long, then our S390-29 could work but you would need to weigh your sash on a scale to determine the proper stamp option for this size.
