Parts to replace

Thanks for posting! I'm sorry to say that I would not be able to identify your spiral balances using these photos. They are a bit blurry so it's hard to make out the tip  of the spiral. Please also confirm the length of the metal tube, the diameter of the tube, and the tip color at the end of the tube. 

If your balance does not have a colored tip, I'll need to know the exact weight of the sash.
