The accompanying PDF file (RAZ-1.PDF) is a Navy Instruction 
Book for "Radio Receiving Equipment Model RAZ-1".  This equipment
is essentially the same as the Radiomarine Corporation model 8503.

The following is a cross-reference table of type numbers:

Navy #     RCMA #     description

CRM-46092  AR-8503    Radio Receiver
CRM-50092  AR-8503-P  Pre-Selector Unit
CRM-20096  RM-6       Rectifier Power Supply Unit

The schematic shown on the last page was originally included in 
the manual as a fold-out, and can be printed on an 11x17 sheet 
for best results.
