All the dimensions are edge to edge:
single coil support: 1 1/4" W by 1 9/16 H
coil balance pivot shoe: 1 1/4" W by 1 1/2" H
the sash is: 20 3/4" W by 17 1/2" H
Unfortunately there are no markings on any of the parts.
The coils on both sides broke, the end that was intact had no markings.
Anything you can recommend will be greatly appreciated.
