That is the one I had.
It was the one I traded with a relative for that had the motor with bad bearings. It worked but was loud. According to the literature in 1981, this motor was still covered.?
I always liked that solid feel you got from locking the door on a KitchenAid. better than the tinny feel of the mid 70's KM, for sure.
Wow, thanks for the postings of the ads and for showing us yours which looks like brand new.
