PS: I can 1X [p=4073c01] in trans red, but I'm not sure.
I can definitely see the one 4073c01 in Trans-Red. At this point in time, we
can look at the timeline for 4073c01 in the catalog and see that the transition
year was sometime around 1992. Since this set was released before that transition
year, it is very likely that this set always came with 4073c01. I will manually
update the inventory to include them.
