The following drawings were located in the same drawer as SY-13xx and SY-20xx drawings, all on buff-colored paper, stamped with date August 13, 1962 and noted "Original in Virginia", presumably at TMC Power Systems.  All of these drawings appear to be for a portable communications system, TMC project SYM-2003.  Numbering follows order in which the drawings were stored.
