Hello, Barbara! Hopefully we can help. The manufacturer of your balance has gone out of business, but I'm confident we can still help. I'll go through each point one at a time.
1) If your shoes and top brackets are undamaged and still working, I see no reason why you would need to replace them. 2) If you are not confident in your balance's color tip, then the only other way to be sure is to weigh your sash on a scale. I'm afraid there's no other way. 3) We do accept returns, yes. You can see our return policy here. 4) Concerning how it installs at the top, I believe your balances are designed the same way as ours. The thing is, the screw hole is usually covered by the outer tube, and it appears your outer tube has broken off. That brings me to another important point: I think you have the Series 600 balance, not the Series 900 balance. You don't want to measure the diameter of the spring, but the rather the outer tube. I can see you still have a balance with its outer tube intact in your third photo. I would measure that to be sure. |

Yes, the measurement you need is the outer plastic tube.
