No, none of these were gov't issue. This was after the war, when they were being bought by hams and Hallicrafters offered an AC power supply to replace the original dynamotor. But I have read that Philco also offered one, but cannot find any info about them. It would not necessarily be the same design. There was no government issue or mandate on these radios, now in private ownership.

At a local estate sale (1985) of former Air Force pilot I bought a 348, it is equipped with a gov power supply drop-in for dynamotor. Some 348's never flew and were used on ground in a military environment thus the gov supply.
