Sash coil balance

A contractor from 11102 says:
This is marked "12" - ok, I'm sure that means 12 pounds. The coil(s) when not broken as these are, extend down either side of the "sash track", where they connect on either side of the pivot shoe.

It is a double hung window manufactured by Crystal Windows, "200 series" I believe.

Thanks for your help.
