Good catch - confirmed my suspicions about the frequency range:

RECEIVER USED W/ RE9175b
300 OHM IMPEDANCE, FLAT FROM 100-6800
CPS.  OVERALL DIAMETER 2 1/32". THICKNESS 1". 
14 OHMS dc RESISTANCE

8/23/43  CQF: PDR-8  USED W/ re-9175
DEC. 44  EXTENDED RANGE.

As an aside, CQF: PDR-8 is what's inscribed on my ARR-3 phones - no 5 
digit Navy number, though.  Looks like the first hi-fi phones!

Also listed is the associated headset assembly, 49455, used w/ RE-9175B, 
JM, and JR.
CONSISTS OF TWO RECEIVERS 49456, ONE
HEADBAND 49453-A, TWO EAR CUSHIONS 49104B,
ONE CORD -49012C, AND ONE PLUG 49034A.

This can easily get into a scavenger hunt with no end...  :-)

Not what the one I have on the web page says - it shows a 49017 cord.  
Makes more sense, too.
