It had no RF stage, and a 96 kc IF, having been design-optimized for reception of radio range signals (150-400 kc or thereabouts) and the AM BC band (up to 1500 kc in 1937).  It also tuned 1.5-10 mc in 2 bands.  The receiver had been modified by WE to "fudge" the AM BC band down so the 500 kc distress frequency could be covered, which lowered the top end of the BC band down as well -- maybe to something like 1200 kc (the tuning cap was straight-line-wavelength, just like most period home BC sets).

That does pretty closely match the characteristics of the WE-20** series 
receivers that are discussed in H. K. Morgan's 1939 book, Mike.  The 
standard 550-1500kHz band would have had to be tuned downward in the 
manner that you recalled.
