If you'll notice, there is a bleach dispenser in the right front corner, so it is a deluxe machine with the narrow post agitator and tape across the control panel, two attempts to hide identifying markings.
Yes, oversudsing could be a problem in top load automatics, especially in perforated tub models. A neighbor used Tide in her 1958 LK and burned out the motor in a year so after that it was only ALL that was used in her machine. Maytag was really on to something with the sliding motor mounts that allowed the belt to serve as a clutch. A Maytag would never hurt itself. A neighbor across the street got a TOL Maytag in 58 and used Tide. She did not have a dryer, but in the winter when we would have rain and cold for days on end, she would wash everything and take it to the coin laundry to dry. The combination of the detergent left in the poorly rinsed clothes and the high heat of the dryer (because she wanted to dry them fast and not waste money at 10 cents for 10 minutes) made the clothes yellow in the dryer, reinforcing her dislike of dryers.
