Are the details from back wall accurate to any instance of the set? I've been scanning through season 2 and I've noticed a couple of eps. they swapped one wall for the other a couple of times. One wall looks like 4 metallic blue doors, with rectangular cutouts in them and a red phone set into the center. The other wall is a bank of guages, switches, and knobs set into panels of various shades of grey. But neither of these are reflected in the radio shack part. I don't have the later seasons so I don't know if these were changed later on.
