Human, I recently saved a very dirty Harvest Gold MM (which looks yellow), and has the black handle and knob, and yellow (almost looked painted) turntable. So what you saw might have been a real thing (unless it was a repainted different unit or parts).
Mine is a model MMA, 175W with PTO. It has the plain aluminum nose cover that pops off to access the screw under it.
I did not need another mixer, but it was on the $1 clearance table, only an hour away from being destroyed and tossed in the dumpster (this particular thrift store does this - PO's me for sure.)
On the same table I got a small white glass bowl (Sunbeam Fire-King) for another $1). I bet it came along with the mixer, not sure of them once being matched or not.
Not sure if I missed the beaters or if they were not included. They sell everything from a set separately in different areas of the store which again hacks me off to no end.
The original price of the mixer was $13 and the bowl $10.
I spent a few hours tearing it down and washing the parts. It looks next to brand new and it matches a GE AM clock radio of the same era (and color). It runs okay but the motor drags - the old grease is solidifying and needs to be replaced after going a complete overhaul. Maybe later for this one - not sure if I want to keep it or not, despite its beauty. I just have too much right now!
