This cog seems frozen so inclined to think I need to unscrew from the back. not sure.

regarding the stuck cog...
I've got the same issue on some SunTour Winner freewheels. I think it's a matter of corrosion and time. The standard fix is to use penetrating oil and let it soak in.
When that doesn't work.... I suppose the judicious application of heat might help, although some will advocate for the use of percussive maintenance. I haven't gotten desperate enough to try those yet.
