Your balance looks similar in design to our S770-22. The only strange part is the stamp; an "HD" stamp is very uncommon for this style balance. While I am confident that our S770-22 can replace the old assembly, you will need to weigh your sash on a scale and refer to the chart we show on that store page to verify the best stamp option.
