   This *might* be "outline 55" in the RCA transmitting tube manual (TT-5; 
1962) but on skimming thru it, I don't find anything that would fit this. 
The Outline 55 has a top and side cap, and is of the dimensions you give - 
but going through hundreds of tube listings looking for a diagram of a 
triode with caps for grid and plate, and *then* trying to find where it 
lists the 'outline' for that particular device...  dang!  I couldn't 
narrow the search down using this latest RCA manual - I have four earlier 
RCA TTs going back to 1936, the full GE set, and an RCA HB-3, the Tung-Sol 
Power Reference, and all the Eimac stuff to go through - but hopefully 
someone will recognize that basing and give you the info.

   If this does not happen, let me know and I'll search further, though it 
will take some time to complete.

   Cheers
