[Milsurplus] BC-348 series CORRECTION

[James Whartenby]

Thanks Robert for these production numbers.  
Summing all of your numbers gives a total of just over a million units.  I wonder if all of the vacuum tubes made during WW2 comes close in number to those made just for the VT Fuze?  It is just amazing that 22+ million VT Fuzes were made in about five years.Jim

One of The Green Books, (The United States Army In WW-II), STATISTICS, dated 09 April, 1952, contains production figures on Signal equipment.  SCR-274-N production was, according to a footnote, not reported.  Instead, the book shows production figures for the three receivers and four transmitters.  The highest receiver production is shown as BC-454 (-A and -B combined) 161,875.  Low is BC-455 @ 145,848.  The high transmitter is BC-457 @ 145,926.  Low transmitter is BC-696 @ 40,620.  BC-456 is not listed.

On the BC-191, 224, 348 and 375, production figures are only given for the radio sets that they belonged to.  OK for BC-224 and 348 and mostly BC-375.  But BC-191 production would have to be arrived at by summing the four sets that used them.  And similar sums for BC-312 and 342 (which I won't do here).

SCR-187 total production is 5790.  SCR-287 is 102,508.  So that roughly agrees to H's figure earlier today of 100,000 BC-348's.

However, the HF Command Sets aren't even particularly close to the set production record.  That belongs to the SCR-536 @ 206,753 followed by the radio receiver-transmitter set used in SCR-522, 542 and 624 @ 206,325.

One of the online texts states production something like 100,000. This number would be exceeded only by the HF Command Sets models, I think. 
For "general" training, such as CW practice, I am guessing the military used less expensive radios, such as Halli S-20's or Echophones. In fact I think I may have a photo of the Echophone being used that way.
As for Cold War buyback, I think I have only seen ads seeking to buy VHF and in HF air, only the ART-13 - not the BC-348, which I thought was odd.
