Where do I find the model number on an old KitchenAid stand mixer?? The only number I find on the botton is T77720A. I do not believe that is the model number.

K4 models seem to mean 4 1/2 quarts bowl capacity and
K5 seems to be 5 quarts

"I have an older-looking K45, but I can't find a serial number. Mine has the model number and volts, etc. stamped into the metal base plate that the bowl locks into. It says it was manufactured by Hobart in Troy, Ohio. It also says DC to 60 cycles AC on it. 115 volts, 250 watts. It's got the stainless steel bowl and the burnished beater. Any idea how old it is? Oh, if you turn it over, underneath it has the number T-77720 stamped into the metal."
