[ARC5] An interesting marking on ARA set sn 4839

[Leslie Smith]

  Hello Clare/All,

  All this is very interesting, Clare.  If I may be so bold as to guess, I think your set has a silver name-plate.  Am I correct?  Do you use this set?  
  I used mine (below) for listening to the AM BC band in bed.  (This is the proper place to listen to a command set.)  After some months it developed instability in the RF (or IF) section.  I'm waiting until I have enough time to properly re-stuff/replace the caps.
  A DIFFERENT SET ON THE SAME ORDER.
  I send a photo of a nameplate from a R-24 receiver. 
  Contract:  NOs 74912.   Serial 2195      12 Volts DC (hand written in black ink).      There is no "stamping" for voltage - only the hand written numbers.

  On the rear panel I see the ARC (in a circle) and then #9603  
  See pg 108 of AN 16-30 - Table 7.2
  Then (on the rear panel)  0.52 - 1.5MC
  11-43.

  On the rear - to the right:  Released 2-43 and the US Navy stamp.
  I don't know if anyone is interested, but I have a photo.

I bought it while I was still working for IBM, so before 1977, at a place in Hamburg, NY called East Coast Electronics.  He had a load of surplus from Calspan Corp. (previously Cornell Aeronautical Corp - a part of Cornell university) And I bought a bunch.  Calspan had several aircraft at the Buffalo airport over the years but I do not know if they ever had a a Ventura or a Harpoon.  Interestingly (or not,,,) I had worked with the Calspan transonic wind tunnel folks while at IBM, doing some custom operating system coding for their wind tunnel data reduction computers.  Standing in the model section of the tunnel was neat as well as was looking at the 13,000 HP synchronous motor that powered the tunnel.> Clare
