Jim -
?
For a given configuration wasn't there a master WD that listed all the components and WDs for that configuration?
?

Sorry, but you don't get to find out.  At Teletype there was a document 
called a B/M (Bill of Material) for each kind of thing that listed all its 
components or assemblies.  So there would be a B/M for LRB21, but it might 
refer to some additional B/Ms for assemblies of parts, so you had to have 
all of them to get down to the last screw and spring.  These were not 
customer documents; I guess they never imagined that a customer would 
want them. 
 
Then there were some things called Analysis Charts, and I have a few of 
those, but nothing connected with LPR and friends.  Some of these just 
cover for example keyboard arrangements, showing how they differ from 
one another, and perhaps who the first customer for a particular 
arrangement was.  Others for things like LP have to tell about all kinds 
of variations and features that may or may not be included. 
 
I don't know whether the sales organization had its own cheat sheets 
to help in deciding which already-released model of something would suit 
customer needs or if a new variation was needed.  And I'm not sure how 
they decided when to create a new code and when to just apply some  
modification kit to an existing code. 
 
If only we had a time machine...
