So, by the picture below you can see that the next machine in my restoration queue is a Smith-Corona. I am in the process of eliminating some of the stickiness in a few of the keys. I have already tried PB Blaster, but there has been little improvement. The next option is a mechanical cleaning with a stiff toothbrush. The schedule for today is light, so I will have some time to devote to getting this one done.
