difference in both the Series 385 and Series 395 balance?

Good question. The Series 385 comes assembled with the 15-001 bottom balance shoe, while the Series 395 has the 15-004 bottom balance shoe attached to it. I am afraid we can't really determine a replacement balance with your images. Is there any way you can submit more photos showing the nylon fittings at an up close view so that we can have a look? Show us balances that have the least amount of damage to them. That would be helpful. Thank you.
