The tanks in the first picture (Potts Motor Park) of Doug's post look like M60s. The rest, like Mark said, are M48A2Cs.
You're right, they have 105's in the three frames shot in Potts. The driver simulators are also M60's, but the other shots of the driving course are M48's. Likely this film consists of clips taken at slightly different times,or at a time when both vehicles were in service in the training brigrade.
The M60 was very much in service when I trained, but not what my tng. unit used...likely demand was still high in the front line units in Germany, Korea and CONUS, so they were using up the M48's. Also, fully half of my AIT class went to Vietnam (almost half to Germany, the others elsewhere), so time spent on the type was not wasted.
