Some of the tube numbers you are interested in may well be industrial  
type numbers.
For individual tube numbers, try this link:
http://tdsl.duncanamps.com/tubesearch.php

For summary data on almost any tube you have or have heard of, get  
Ludwell Sibley's book "Tube Lore".

For lots of odd data on foreign tubes and their US equivalents if any,  
search for the file:
TubeEquivalents_AS.xls
(It seems to be at:
frank.pocnet.net/other/equivalents/TubeEquivalents_AS.xls‎   )

For old military cross reference to civilian type numbers, find the  
file:
vt_to_jan3.txt
seems to be at:  www.tuugo.ca/Companies/spl-systems/0080004723580‎
But that link does not work to get the file.

Try:  aade.com/links.htm‎
for the file vt_to_jan.txt

For extensive data on most any tube made by RCA, search for this:
"RCA HB-3 MANUAL"
and download whatever sections you need.
