[ARC5] BC-454-B Power

Ken's comment that 
"I know that too, Brian, but the 6F6 is a much taller and fatter tube and won't fit in the radio with the covers on", 
reminded me of this: the GF transmitter has a tube cover that is raised higher than the rest of the transmitter top
surface. It's almost like an oops, modification of an earlier design to fit the taller 837 tubes. It must have been much
more expensive to cast this raised cover than to simply cut a flat metal sheet to cover the tube compartment. 
Anyone know the "why" ?
