Hello, all:

A 1929 memorandum describes to types of high-priority, time-sensitive message traffic: x, and rx.

I'm used to seeing Day Letter (DL) and Night Letter (NL) designations.  Were these additional classes in existence for many years afterwards?  Does anyone recall other special categories of Western Union messages?

Good afternoon,
