This page will have information about the General Radio Company which in many was a model for HP.  There is not much here now but more is coming.

The following link is to a scanned collection from the 1920s to the 1970s of the publication, The General Radio Experimenter, available for free download.  These are excellent journals and were the inspiration for the Hewlett-Packard Company to publish the Hewlett-Packard Journal.  Even though these are old, the concepts in them are timeless and are an excellent source for information.  There is also considerable history and other information related to the General Radio Company.

The following links are to jpg files of scans of the General Radio Company 1939 Catalog  which was known as Catalog K.  These scans pertain to Oscillators.  The Type 713-B oscillator was the competition for the HP200B.  Note that its price for the rack mount version , 713-BR was $510.  Compared to the $57.50 price of the HP200BR (also a rack mount version as denoted by the R suffix -- which was not always used) then the nine units (nine for $57.50 each as confirmed by Chuck House during research for his book, The HP Phenomenon) that Disney bought from HP was only about the cost of one General Radio oscillator and the HP oscillator was significantly smaller and lighter.  This was a no-brainer decision for Disney.  The following scans are high quality and are several megabytes each.
