VLS had a great C130 H Book called Lock On N3, C130H / AC130 E Hercules. I bought it in the mid 90's awesome stuff. Somewhere i also have a Squadron book, not as good, IMHO, but workable.
Check with the near by air force bases, they usually have 130's show up all the time at air shows. You can also find a squadron call their public information officer and tell him what you are doing and see if he can help. I had one send me some pics at the time i got the book, i was working on trying to converta an H to an MC 130E.
