Hood/bonnet styles

[abcman3000]

As far as I know there were 4 hood styles differing mainly by the power bulges.

1) NO POWER BULGES AS series with the Fiat badge on the hood, BS series and BS1(USA version) without the Fiat badge
2) SMALL POWER BULGES BS1-european (no badge)
3) MEDIUM BULGES CS, CS1, CSA (USA versions badge, European NO badge)
4) BIG BULGES CS2, CSO, DSO (with badge on the hood)

Am I right about this ? Please correct me if I'm wrong.
