Are you looking for the cover model with the chainbrake option, or without? they were available either way...
Happy to send you an OEM one without a brake set-up. Unfortunately the one I have with the brake set up is the old style and the band is broken.
The aftermarket one works pretty good, not as good as OEM though. The handle is a little "soft" and really needs the third rail that lies in the middle of the handle on the OEM ones. I have also had a problem with it just "activating" on its own a lot.
If you just need a cover to run the saw though, PM me your address, you are welcome to this one...
