Mixers
Lucky finds!
The Iona model you have was rated as one of the best 3 speeds mixers by CR during the mid-1060s. If I ever found one, I would be keeping it for myself.
The GE mixer is a model 15 or 17? Is the cord detachable? Is the plastic housing white or yellow? If it not badly scuffed or scratched it should clean up nicely. It easy to dismantle and service. The gears are plastic and wear quickly when used to mix cookies or other heavy mixtures often. The beaters wobble a bit while running due to their loose fit too. A good mixer for light duty.
The Mixmaster Junior is a nice mixer, it has 65 watt motor, more durable in construction than the other two mixers. Replacing the cord of this model and others having all-metal housing requires one to dismantle the entire motor. Guess they were easy to assemble in the factory but time consuming to service. Replacment beaters are not easy to find and some members here may have some to sell.
