You have an older style coil balance assembly that is discontinued and no longer made. The good news is that we do sell modern components that can replace it: see our 15-177 pivot shoe and Series 152 spring. 

It's odd for your spring to have a letter on it instead of a number; that's supposed to be the weight rating. "F" in this case might mean the same thing as a 6 pound rating, but I'm honestly just guessing. You may want to weigh your sash on a scale to verify. Assuming you have one spring per side, with 6 pounds of support each, that means your sash should weigh 12 pounds. It's worth checking.
