?   As I recall, the Model-T used a natural convection cooling system.  
Do you drive a Model-T,?

?  When a fan blows on the side a cylinder, the air flow bends completely 
around the cylinder.

?  Eimac makes mistakes from time to time.  The grid design in the 
3-1000Z (and 3CX1200A7) are examples.

?  The split chassis/slow-speed fan cooling system works best with a flat 
ceramic socket.   E. F. Johnson virtually owned that market.
