definitive list of cases for each model calculator

[Kostas Kritsilas]

I think that over time, there were a vast number of small, but significant variations in the cases, as the pictures of AndiGer show. My recollection of vinyl colour variations is another. The cases did not vary in terms of actual physical layout, but vinyl colours, textures, flexibility, zippers, and possibly the inner linings I think would be common, and in many respects, expected.
