Had to call the wife in on this one. Blenders (as near as we know) are not normally highly sought after. That said, you have the complete set, which is something we've never seen before. Normally you find the attachments selling separately.
A few years ago we were at a local small-town auction and the wife picked up a Kitchenaid 300W mixer with bowls for $60. It was mint condition, but was never cleaned after its last use. Works flawlessly!! It's actually her go-to machine, as she doesn't want to wear out her new one (still to this day not ever used).

Your bowl is classic beauty! Makes the Cream-n-Green theme stand out!!
Wife asked me if, in your shoes, if I would repaint the body or have it professionally repainted. I told her I didn't think so, as that is much of the character - much like the patina on a coin or relic. At most, I would have it clear-coated to protect the original finish. For the cord, however, try to find a replacement that is as identical as the original. Nothing...and I mean NOTHING will detract quicker from its value than to have a more modern cord installed!! Find an older cord for sale - maybe from an appliance that no longer works.
Yours is quite old, as we can't remember when they last used the geared beaters (2 beaters with 1 insert shaft). That's awesome!! And your attachment was, for its time period, a food processor/meat grinder. Neither of us have ever seen such a complete set as that for that old.
The bowls look like they're well taken care of. That's a plus! And the juicer attachment? Awesome!! ...Well, that's all for here. Gonna send you a PM with a few more comments.
Great find!!
