[ARC5] 10-Meter 274N RX - The 20-27 RAT-1

I've only been doing this for about 52 years.  The manuals that I referred 
to are properly printed with photographs, properly printed chocolate brown 
covers and properly glued bindings.  They were printed before the NAVAER 
numbering system was lit off.  I have several dozen of the early preliminary 
manuals like you described.  If these had been some of those, I would have said 
so.  Generally, if a no-number manual got assigned a NAVAER number stamped 
on a white stick-on label, it meant that the Navy had decided that there was 
no need to print a new manual.  As an example, most of the early model LM 
manuals are like this.  Even some of the black mimeographed manuals fall into 
this category, especially those on DF sets.
