Is there some location in the Teletype world that began with the letter R?  Here's why I ask....

KS stands for Kearney Standard (or was it Kearny Specification, my memory is going), Kearny as from Western Electric Kearney Works in NJ near NYC.  That's probably where the concept of WECo standards developed, but when I worked for the Bell System (Bell Labs 1979-2000) I doubt that the people then writing KS specs were physically located in Kearny any more.  Around the mid to late 80s there was also WP specs, WP being Western Preferred.  If I remember right WP meant that some part was double coded by the Mfg (meaning the Mfg assigned their own part number and whatever WP number WECo told them to assign, and the mfg promised not to change the Mfg's spec (whatever the spec was originally) without the approval of WECo.
