This is the spring we need to replace at one of our properties. We're hoping to locate the manufacture and purchase asap! Thank you for your time and expertise!

Paul from SWISCO responded:
Hello! Many manufacturers use many different kinds of balances, so knowing the manufacturer alone is often not enough to identify what you have. We recommend basing your replacement on the hardware itself. For example, our 15-177 pivot shoe is similar to yours, and uses the Series 152 coil spring. Check out our dimensions, pictures, and information to determine if they match up. There should be a number printed on the spring itself to tell you what strength option you need.
