Antique Musical Instruments/Euphoniums - Baritones


What does "US" engraved just below the Holton engraving actually indicate?  USN, USMC, and USQMC are pretty obvious, but "US"?  I have now encountered it on a second 1940ish Holton euphonium / baritone.  My eyes say the Fonts for the "US" were identical although I did not have side by side pictures.
Reference my old question on Buescher Euphonium mouthpiece shank / receiver sizes.  Have since then encountered several Internet comments on other Buescher Euphoniums describing the same phenomena of requiring larger than tenor/small, but smaller than euro/medium shanks.

I'm not certain on the US marking, but have always assumed that they were acquired by the Quartermaster Corps, and were just abbreviated US to indicate that they were purchased for military use.

Regarding the receivers.  In the early decades, there was no long shank trumpet, cornet, trombone or baritone mouthpieces.  They came later.  The short shank versions have a slightly different taper than the long shanks that we currently use.  And, they were not fully interchangeable.  Some makers made them larger than others.  In other words, there was no standard accepted by all makers.
