Polybau balance replacement

A quick learner from Whittier, California says:
A balance broke on a bathroom window, we had all polybau windows installed 10 yrs ago this is our first problem & polybau is out of business. Looks like the manufacturer is prima products inc can't find them either. It's a single hung window, balance patent #5697188 measures 2 1/2" long & 1/2" width. Hoping you can help.

We may be able to help. How about our 15-213? Could this be a possible match? Carefully compare it to your own hardware and let me know what you think.

That looks exactly like it, I will re-measure our part & compare hopefully this is it. Thank you so much.
