[Milsurplus] BC-348 with mil AC supply

[WA5CAB at cs.com]

Hue,

The date stamp on the capacitor just means that the capacitor was made 
before VJ Day.  The supply (which sounds more nicely done than the Hallicrafters 
EP-298) could have been done up to 1955 or so.  As DA and then DOD still 
had ample supplies of BC-342's in inventory and as budgets began once again to 
be slashed in September of '45, I can't think of any good reason why the 
Army or the Air Force would have paid for the job.  More  likely it was done 
for one of the airlines.  Like the crystal mod to the T-47A, which was only 
later bought by USAF and called T-412/ART-13B.
