Coil balance assembly - I think

Question

Ever seen this odd thing before?
This is the only one still intact, the others are missing entirely
(Maybe conversion to spiral makes more sense, but I wanted to try
to find something similar to original first)

I'm afraid that the manufacturer of your coil spring balance system has gone out of business. That said, we think you can replace your balance system with something a little easier to use. Please see our Series 140 coil balance system. The only question is, what specific Series 140 do you need? In order to figure this out, we will need you to tell us the weight of your sash and how many springs are used on each side. I will also need to see a picture of one of the old pivot bars out of the window; since it won't be compatible with the Series 140 we will need to find a suitable substitute.
