Hi Larry,

A little searching on the web will probably yield the answers you seek.  
The Duncan's Amps site offers a pdf data sheet, complete with curves, on 
the Cunningham CX-301A in the lower right hand corner of this page:  
http://tdsl.duncanamps.com/show.php?des=CX301A   

Another site indicates that the 01A was the equivalent manufactured by 
RCA in the late '30s.  A simple Google search for Cunningham CX-301 will 
produce several pages of listings to research.

There are some neat sites out there on the web that have an amazing 
amount of vacuum tube data available for downloading.

73,
