I think I can already answer this question BUT here goes.

In my collection I have a Colour Classic and a Color Classic. As far as I know, same model numbers too but I will double check. I don't know if you'd want to include this variation or leave it off (especially if they share the same model number).

And the Classic has a variation with and without speaker holes - again I will confirm if they share the same model number as I have both in my collection too.
