Well, not really. There were some cutaway drawings of nuvistors; as
near as I can figure, they're just ordinary vacuum tubes except made
with metal rather than glass shells, and with somewhat more
mechanically sturdy element mountings. Novars I still don't know
anything significant about besides the numbers in the table.

One of the products advertised in the book I have is a five-binder set
which "contains over 5000 pages of loose-leaf data and curves on RCA
receiving tubes, ...". Price "$20.00 including service for first
year", but without specifying what "service" is included.

And it's called the HB-3. :-)
