Original old brushroll degraded to make sweeper-like sounds of Heritage II. I bought this as a last resort. It's wearable. It's installed. This solved the problem. So, in 1986, Kirby lives on. Works great. The brush looks exactly like the one Kirby Corp sends as a replacement. The new brushes are different from those that came with the new Heritage II models (the original had a metal case engraved with a number).
