Window balance

There's a very good chance we can help with this balance, but this particular assembly is too damaged to ID. All I can make out is the stamp, which is helpful, and the pulley block, which is the same style used on dozens of different assemblies. 

Do you have an undamaged version we can see? I specifically need to see the top end, bottom end, the pivot shoe, and whatever clip or hook is at the end of the cord.
