This washer is a unimatic machine and the lower one is a pulsamatic. Those were the two mechanisms Frigidaire made at this time. If I am not mistaken, I think this was in 1955. The pulsamatic machines had a shorter, faster stroke. It was almost a vibratory action, it was so quick. The agitator for most of the pulsamatic machines was the one piece black bakelite one, although the later ones had grayish plastic top agitators with the cap and dispenser inside the top piece. Once upon a time, in the mid 80's, I picked up a Frigidaire pulsamatic machine like the one in the bottom of this POD and instead of fixing it, I junked it out and used the tub since I needed it for another machine. I have regretted that ever since I realized later that it had been a pulsamatic machine.

The '55's were great survivors. Plenty of them around. I remember when they were all over Atlanta. I always loved the yellow ones because I thought they looked good with the black Detergent Column and Energy Ring. The trim had a lot of yellow anyway with a great looking badge on the front of the cabinet. One of these was my first Unimatic restoration. A very interesting journey.
My grandmother had a Unimatic, it washed clothes really clean with little wear and tear. I do remember horrible tangling though, literally in ropes, and high suds.
Sure was fun to watch.
