It woulda fit Jeff. It fits them all. There is more than just the pump/gear/rim, there's also a crank bushing and washer that's needed.
I have 2 setups here. The non adjustable oiler works better and puts out more oil than the PRO setup. The standard oiler is nice on a ported saw. If you need to use a longer bar in a pinch, you can let it idle a bit and blip it to oil the big bar. The pro wont do it.
I used to be quite wrapped up in the entire pro oiler setup till I realized the standard was fine for the job.
This one has the standard oiler. Slow, but did the job.
