Well I am a Mopar guy and my dad worked for Studebaker back in the fifties, so my knowledge is a tad limited. The first one he had was a V8 so it was a Commander. The black 54 I found for him was a six so I think they called them Champions. The two hatches on the front fenders behind the wheel well was to open up to let fresh air in. I am pretty sure but I may be mistaken.
