Found when you could buy these full wrap handles they were listed at $155 a piece.

Guess thats why they are high NOS.
Being I never had a gen1 5200. What is the difference if any in the full wrap on 52 to gen2 gen3 5400 8500?
Number is different in 52 but same on 54 85. So maybe the number just superseded?
poulan 4200 5200 av anti vibe mount = Kensie - part number is 530024225, it is the updated version used on the 3400/3700/4000 rear mount, and all of the 6900/7700/8500 mounts. I've seen them on eBay from pro line and chainsawr.com is also selling them, which is where I got them.
