Glenn, if this is a true LK, then it had a medium temperature too. That was the "exclusive" feature for LKs of this period. After these center dial Kenmores came out, they stripped pretty much all features on their dryers. Temps were only air, low/delicate, high/cotton sturdy. The LK was the only one that offered medium. And, this was an early version because it had 4 auxiliary knobs--temp, signal, start, and wrinkle guard off/on. The next version of the mechanical LK model had only 3 aux knobs. Did away with the WG on/off knob. This was the only dryer in all the years of center dial Kenmores that I found acceptable. All other models had cheapened features as far as I was concerned. Lesser model dryers with the same temperature switch arrangement did only offer low/delicate, air, and regular heat temps.
My DD LK dryer didn't offer a Wrinkle Guard on/off knob. And when comparing that dryer to the one above, I was very disappointed. I hated having to get up go out to the dryer and either turn the timer dial to off or open/shut the door to cancel Wrinkle Guard. Really p'ed me off.
