Extended-Travel Channel Balance Quote

I'm not sure what you have, unfortunately. We have dozens of different balances with that stamp. It's not a product code or anything, it just indicates the strength of the spring. Our service requires clear and unobstructed photos of the hardware in question at minimum.

In order to figure out what type of extended travel balance this is, I need you to remove an undamaged version of this balance from the window and show me clear pictures of the top and bottom nylon fittings, as well as the metal clip at the end of the cord.
