Trying to ID a (Peter Yorke) cue in a 1950s Caterpillar bulldozer film

Hello, I was curious does anybody know what the music featured in beginning and end in his industrial film produced internally by Caterpillar tractor in the late 1950s might be?  it sounds similar to some of Peter Yorke's industrial cues such as "Energy" and "The Lathe" ("The Lathe" is the music that proceeds this theme during the model demonstration), so I'm guessing he might have done it?
