I am not sure the tubes were made by RCA. The tubes have the square getter, but not the common RCA upper mica that is cut on two sides and contacts the glass about 60%. However, some RCA did not have the cut top mica in the 1950s. The tubes are not Amperex either as the tubes do not have the folded glass on top. Also, that getter type was not used in the 1960s per seller. They are 1950s series tubes.As for best sounding 12AU7, look for either Brimar 13D5 or CBS/Hytron 5814. I have no idea how the RCAs sound.
