I'm sure someone here will have it - I got a Hitachi number from some folks on here. It works really well on the M and I have one on my A also. With the M the installation was easy. With the A I had to weld up a mounting bracket. Still works really nice there.
If no one comes up with that Hitachi number I can go out to the shed and get it. I've been meaning to find a reason out of this house anyway.
