Seeking photos & records of 1st Battalion, 7th Special Forces Group in Vietnam or other conflicts

I am a unit historian for 1st Battalion in 7th Special Forces Group. I've been asked to find out more information on our Unit's History, specifically around the Vietnam era but after that as well. I've found connections to Project HOTFOOT and Operation WHITE STAR in Laos and other articles claiming involvement in ARVN training but can't find any pictures, official records, or names of personnel involved. Any help would be greatly appreciated!
