Bought the wrong one for my machine and didn't notice it.

New, no box.

The diameter of the inner mouning circle is 3 inches. there are 12 teeth. Hopefully, that will help you with fitting. I think this is for the AutoIQ system.

These are usually $70+ without the blades. This comes with both the blade and dough blade.

Feel free to bring your base and give it a try for fitting.
