Hey there Phil, the machine I found is a WIAS-1, not a WIAS-2. The '63 models are the "-1" and the '64 models are the "-2". Confusing, I know! These are somewhat rare outside of the standard models.
I wish I had docterine that talked specifically about the WIAS-1, but alas I do not. The owners manual is also dated from the fall of 1962.
Thanks again everyone! I ended up spending several hours fiddling with the '63 washer tonight. I figured out what is wrong with the timer, and I need to stop by the hardware store tomorrow to pick up a new set of belts. If isn't going to take much to get this old girl up and running (thankfully I've been gathering multimatic parts for quite some time.)
