That's quite a list of handles. Although they have lots of different part numbers, the main difference is the colour of the rubber and the width. All in all the big ones will fit the big saws and the smaller ones will fit the smaller saws. With the narrow handles, removing the clutch cover on some models may be difficult.
Here's my newly aquired Poulan Pro 655. It's all original except for the black caps. Most of the screws have never been loosened. Not pictured is its 36" .404 bar with most of the original paint. I can still make out the wording on it. The chain is about 80% or better and is soaking in my varsol tub. The rear plastic handguard is cracked and needs replaced. Overall it's in excellent mechanical shape with good compression. I'm going to put a K&N filter on it.
I think these are incredible saws but I don't hold them in as high regard as their older Pioneer bretheren... it's the colour or something. Or maybe it's just their rarity.

P.S. welcome back Jerry, hope you had a great vacation!
