&Seeing John's '59 LK makes me want to kick myself again for getting rid of my yellow one. Having grown up with a '60 Model 80 (same type of pushbuttons as the '59), I just didn't think it was all that special. And yes, both machines suds-locked all the time.
I've never seen the '60 LK in person, just in the above photo. If only my parents had sprung one model up in the line. Sigh.
The only difference in cycles between the '59 LK and the '60 Model 80 were these:
1) The white SPECIALS button had COLD WATER WASH on top and RINSE SPIN on the bottom. (The '59 had no rinse/spin cycle)
2) The pink SPECIALS button had WASHABLE WOOLENS on top and SPIN ONLY on the bottom. There was no control for the console/tub lights on the '60. The light came on at the beginning of the cycle and went off at the end. When I had my '59 LK, I used to turn off the lights in my windowless laundry room and load by the light of the w & d consoles and the tub light. Sigh, again...
There is also a TOGGLESWITCH (Hi Tog!) on the right (I think) side of the console on both the '59 and '60 that adjusted the medium water temps to warm, and the warm water temps to cold (including rinses).
AND, if I recall correctly, I believe the Light Soil Delicates cycle and the Washable Woolens cycles were identical. Warm wash/rinse, 2 minutes agitation, slow spins.
