That's because of two issues.
1-The USAF was tighter on the control of it's retired publications. We were always required to burn or shred our regs and tech order pages when they were updated or changed. This is why you see a huge supply of original Army pubs on the market. The Marines & Navy also were as tight as we were.
2- The lack of photos comes from the Air Force's primary mission. Aircraft. Thus you see plenty of aircraft and very little of ground vehicles. During my 22 years in the USAF all of my photo taking on the job was focused on the aircraft.
100 BW would only be found on bumpers of vehicles assigned to the wing HQ squadron. Units that made up the 100th BW (M) at Pease during that period were:

100th Air Refueling Sq. (ARS) with KC-97's.

The wing's 393rd, 715th, and 830th Bomb Squadrons (BS) with the B-47. 509th Air Refueling Sq. (ARS) Tankers
