Call HandiQuilter and ask them outright!
When I was buying my SS, they were very helpful in helping me sort out the differences between all the rebranded/painted versions of their original SS.
One thing to note is that the SS is now into the 3rd generation/evolution (maybe 4th?).
With yours being virtually a SS, it would be important to know which version it matches.
That will determine what options you have for it.
