Hello, We believe that your balance system was made by a balance company called Unique, which went out of business quite some time ago. For your 530C pivot shoe, customers have found our 15-046 1-1/4" wide by 1/2" thick pivot shoe works as a replacement. We also believe you have an S600 tilt balance but your spiral is missing the bottom pin. We will need the diameter of the plastic tube and length to confirm. For the spring strength, please look up into the tube where the spiral comes out for the color bearing or provide us with the sash weight. Thank you! |
