Hello! The pivot shoe looks like our 15-134. Check it out and see what you think. As for your balance, it sounds like our S900-34, however 40 pounds is pretty heavy for this kind of balance. Can you confirm? I don't think we have a spring strength option for this balance that can support that kind of weight. You said your color tip is green, which is indicative of a sash weighing 14 through 26 pounds. Please double check for me, just in case.
