[Milsurplus] RE: BC-312/348

Hi Hue and the Group
My only guess about this point is that the -224A version is like the -312
simply because that was the starting point.  In the -224B "the form
follows function" rule would apply.  Low weight translates to light
aluminum alloys but the requirement for frequency accuracy translates to
a rigid frame to hold the tuning mechanism.  It is interesting to note
that the aspect ratios (length width height) are approximately the same
for each radio.  The -312 is taller but the -224 is deeper.  I'm sure
that the redesign to make the radio lighter for aircraft use resulted in
the final production radio form.
This is all guess work 60+ years after the fact.  I had tried to locate
contract reports but was told by Smithsonian curators that none have
survived that they were aware of.
Any out there?
Regards,
Jim
