Datasheets for essentially "all" EIA registered tubes (including CRTs) are available as pat of the "Tube Data Cache" CD from the Tube Collectors Association.

The listings go up through the very end of the CRT era, including the WTDS types used in later monitors and TV sets.
The $50 price may seem a bit steep, but it will replace a whole shelf full of tube manuals, and also covers many types from manufacturers that never published official manuals. It also includes information on the various revisions and changes a tube may have undergone during its production history.
