VT-1 tube data can be found in "Principles of Radio Communications"https://archive.org/stream/principlesofradi00moreuoft#page/554/mode/2up
on page 573.  Don't know what you mean by accurate since tubes of that era were a crap-shoot.
I have a few VT-1's to lend, if this will help in your testing.  Some used, some NOS.Jim, Hot Springs, AR

I am thiiiiis close to firing-up the BC-9.  Got to
find a better sub for the RF Osc/Det.  The 01A
works fine in the audio amplifier but lacks the gain
to oscillate in the RF stage.  With a change in bias
battery, a triode-connected 6AQ5 will oscillate but
I would like to find a better match.

Does an accurate datasheet for the Western Electric 
VT-1 tube still exist?  Google is no help at all.  
There is a ton of incorrect stuff out there that gets 
repeated and repeated, mostly equating this 
01A-like tube with the 203 transmitting triode 
or listing a few specs that are completely bogus, 
like the wrong filament voltage etc.  
Anybody?  
Thanks.  73 DE Dave AB5S
