The 5-digit code:  08594 

  

They have been called FSCM (Federal Stock Code for Manufacturers), Cage Code, and now known as BINCS.    Some codes are all numeric, some are alpha-numeric. 

  

The code 08594 is assigned to Varian Associates in Salt Lake City. 

  

To find these codes search BINCS.  Actually BINCS is a search engine that allows searching by several different criteria.  Here is the URL for the site I located the info.

Thanks for the replies 
There are two codes on the tube, 08594 and 6948.  I've been told that the 
second is probably the date code (week 48 in 1969 ?) but I have been unable 
to cross reference the first to a manufacturer.
