An RCA Receiving Tube Manual is a good thing to have. They diagram each tube and have the pin numbers (bottom view).
For the older sets with tubes like the 42 you should have an older manual, as the newer ones list the older tubes in the back of the manual but do not include the pin diagrams.
FYI a tube substitution manual is another good resource to have on your bench.
