Mea culpa
Sorry, it was the SD-400A, as noted on pages 530 and 533 of the November, 1965 issue of Consumer Reports, that had the trim piece on the front of the upper rack that was the dirt catcher. The modified model without the trim piece was SD-400B. Both the GE SD-400A and the SD-200A came in dead last in this report. CU stated that removing the trim piece might help with the redisposition of dirt on the inner door, but it would not improve the washing performance of these machines. How low the once mighty have fallen.
In this report, the Check-Rated machines were the Westinghouse SUF-4A, the KitchenAid KDS 15 and KDC 15, the Whirlpool SLU90-4 and the 70-3.
