I would say that KM is indeed a direct drive. Not only that but I'm betting that its one of the first, making it a direct into spin or spin drain model. It looks like there is a clear plastic 'cover' on the timer dial to prevent turning the dial while its running. I think that was only done on the 'D-2000' models?
Gordon, Thank you, for remembering, our Mom's did indeed have the same 1974, Same layout as the later "black panel" machines, the 74's had brushed chrome. Always a pleasure to see your posts. alr
