Jon and Charles et al -
When you got your 1970 machine Jon, it prompted some debate about the lineup of the time. As a result, I did a lot of research on the various 900-series models of the mid to late 60s, and learned some interesting stuff.
Per an e-mail from Andy, this machine's model number is 110.6604911. There is an S in the model number plate that threw me, but if this machine was a suds model as some including me first surmised, it would have model 110.6605911. The '5' stands for suds model automatics, '4' just automatics, and '3' for semi-automatics where the user defines water temps at the tap...(getting off topic tho).
Oddly, the "real" 66 Lady's model number is 110.6604900 to 110.6604904 or 110.6605900, etc. I believe (just minor engineering revisions). I do not remember what was different about the '910 series but for some reason it didn't qualify as a Lady. There was a 920 and a 930 series also, which is really odd, the '930 being only a 2-speed machine and had a Super Roto-Swirl as it's agitator.
Sears was either price-marketing these separately from the Lady, or possibly there was a shortage of something that distinguished the Lady and warranted a new model number. I simply don't know, but I was surprised to see the '920 and '930, so seemingly identical looking on the parts diagram, but with a Roto-Swirl, etc.
This washer was made in 1968, so perhaps by then even though it was a '66 model, the revised '68 Lady was available so the '66 family tree had to soldier on as 900s without the Lady designation. I think by 1970 the de-throned 900s went on to become 800s as the fancier models came into the Lady lineup (they would have an 8 in the model number where these have a 9).
I don't remember what my '66 Lady had as far as a soak cycle. It was one of the 21 stolen from me so now I can't check and compare. This could easily be something that distinguished one model from another in those years.
