Hi y'all. I'm looking at replacing my Suntour freewheel with a Regina Oro. My Suntour is currently on my Campy High Flange hub but what I'm not sure is the type of threading (English, Italian or unlikely French) that I'll require for my Regina.

Is there any way to tell what kind of threading is on my current Suntour freewheel. The only thing I know is that there are two notches to remove the existing one. So I'm also assuming that I'll need the Park FR-2 to remove that too.

Any help would be appreciated. Thanks...
