Info on RCA binder-type tube manuals?

[Fred Olsen]

Those are the older style all-in-one set, Mike.  They were a
subscription type service, with periodic updates as new types were
introduced.

How useful they will be depends on a couple of things.  The original
edition number or copyright date.  (I can't specifically address that
due to "I dunno" regarding various editions.)  Whether or not the
subscription was kept up, and for how long.  And, if old types are of
interest, whether or not the obsoletes were pitched out, perhaps due to
lack of room in the binders.

They look fairly 'thick' with info, so maybe you'll get lucky and find
that they contain every number you ever heard of.  Sorry I can't be more
definite.  Anyone who can expand upon this, or demonstrate how dumb I
am, is welcome to.
