Hi Skip
Another way to figure out which pin  is which is to study the wiring under 
the tube socket with the chassis upside  down ,and figure out what are the 
filament leads,the control grid ,the screen  grid and the plate(I'm assuming these 
are screen grid tubes since the Grebe  dates from 1933) .This provide a double 
check on the data you already  have.
