Wow!
What a spectacular machine - that is my idea of a real washer.
My mother's 1961 had the same scrubber, but she actually used hers and it was worn probably 2/3 down (her model didn't come with a detergent cup). I found one of those (ok my friend I met here did) Easter weekend when we went scavenging. Now I just need a proper vintage machine for it.
Concerning the suds savers - Robert is right I think - there were lots and lots of suds savers in the older parts of Michigan where I spent 10 years of my childhood, and more yet in the older town in New Jersey where my folks grew up. Places with basements, double cast iron sinks, OR houses with a single tub could use them.
I don't think I've ever seen a suds model here in Charlotte - almost nobody has wash tubs. Suds models were often available as a sub-model of the basic issue. Not every machine was available with the suds option, but most were, especially in the "bread and butter" portions of the line. There is only one digit difference in the model number.
Again, such a cool find! I don't know what it is about the '63 model - I have seen a couple dozen over the years, in turquise, coppertone and white, in fact several of my friends moms had them. I've never seen a '64 model though, and only one '62. Strange....
Thanks for the pictures!
