I have a PDF version of the manual (file name ST-32-152.pdf), and it is 
available at:
<http://www.r-390a.net/ST-32-152.pdf>  Also, I will mail it to anyone who 
asks for it.

The title is:

ST 32 - 152
VISUAL ALIGNMENT OF RADIO RECEIVERS
R 390/URR AND R-390A/URR

USASATC&S 32-152
March 1959


Notes:
  1) The title uses the word "alignment" but the word "alinement" is used 
in the text.
  2) Figure 5-4 is supposed to be a sine wave but actually shows an  S- 
hook shape that is not possible as a diagram of a voltage over time (But 
you can get the idea.)
  3) Some of the information relates to non-retrace-blanked situations 
where the RF sweep is derived from the line voltage and is a sine wave. 
More modern sweep generators will be more convenient to use.
  4) The majority of the procedure is for the R-390/URR (the "non-A")  and 
a brief description of the procedure for the R-390A/URR is given, with many 
statements that it is the same as for the "non-A".
