:: Valid point, so long as we retain mention of the notable variants in the text (these being 75 ->76 mm gun, HVSS, addon armour "Jumbo", Firefly, and that it was adapted for specilaist roles as well (DD, Crab). I think that a table might help the layout as well if only just to show the US->British nomenclature since they aren't actually variants just other names for the same thing.
