In my search for photos, I came across a two websites with quite a few Herk photos, all years and models:

And this website with a ton of information involving all things C-130s:

Every job assigned to the Tactical Air Command requires one special talent: mobility… more “get-up-and-go.”
TAC’s new combat cargo plane, the C-130 Hercules, represents a new era in mobility. It’s the first military transport with turboprop power. It’s fast-faster than many commercial transports. It’s eager- able to take off and land in less than 300 yards. Designed for rugged and robust work, it can use even improvised runways.
First assignment for Hercules: providing a mobile airlift at a moment’s notice for TAC’s 18th Air Force. Hercules will fly cargo and men farther, faster and at less cost than any other combat transport. The job of quick resupply is a good example (and just one Hercules’ dozen or more prime missions). After dropping 64 paratroops, or landing supplies or 90 infantrymen in combat zones, the Hercules can hustle back to advance base, load up with some 20 tons of food, ammunition, medical supplies, and deliver them where front-line fighters need them. Then, converting in a matter of minutes to a hospital plane, a single Hercules can evacuate up to 71 litter patients.
This takes get-up-and-go. TAC’s Hercules has it. Designed by Lockheed, the Hercules is now in quantity production at Government Aircraft Plant No. 6 in Marietta, Ga., America’s first turboprop production line for transports.
