This machine is about 1957 or 58. The reason I give that age is the design of the protective grid over the impeller. Our neighbors had the roll out version of this with the same Plastisol-coated grid and they bought their DW a year or two before we bought ours. Ours was a 1959 or 60 and the protective grid had openings that were one-fourth inch in a stainless steel hardware cloth style, no more plastic coated grid. The first year of the new design had even larger openings in the grid than Dan's machine. Once or twice we had the little flat seal that goes on baby bottles fly out of the silver basket and make a racket as it was dragged around under the grid. We stopped the cycle and I managed to work it across the grid, since the plastic disc floated, and then pushed it down and under the edge to retrieve it. There were no closed portions of that silver basket, but we usually figured out ways of keeping things from flying out of it. One of the really neat things shown in the manual was the use for the five slots on the end of the silver basket. Those openings were where you put long-handled cooking utensils like spatulas amd spoons. Our neighbor used to hang cups by their handles from the pins across the back-center of the opening. Each set of pins on the edge of the top rack that rose straight up from the rack had a pin between them that was positioned slightly forward and it was from those that she let her Franciscan cups swing and sway.
Dan, I noticed that the little curved end of the detergent dispenser seems to be missing the little piece of stainless steel that is supposed to fit inside the curve. It was stainless steel with a high enough iron content that it held the cup in place by clinging to the magnet on the shaft of the timer dial that went through the tub wall. After the wash fill, there was no more magnet and the bottom cup dropped so that, unlike some D&M machines, it did not dump the detergent until there was good water circulation. That was why it was so important to remember to close the clamshell lid to the cup, because if you left it open so that it looked like two cups, it would not release. That happened one night and we were wondering the next morning why the baby bottles were not super clean like they usually were, then I looked over and saw the detergent dispenser open with water and detergent sitting there. If you look at the impeller and see the direction it turns and then at the way the detergent cup falls, you will see that the two waves of water flying up from the impeller caught the open cup and flushed out any detergent that did not fall out. GE changed this cup to the slightly larger cup with the hinged cover so that it would always dispense, further assurance for which was gained by the little barrier in the part of the rack right in front of the dispenser: to keep everything away from the area that might prevent the dispenser from falling open. Incidentally, these early versions of the GE had 3 after rinses. And it was not a D&M built machine. It was all GE.
