I has a simple inlay around the soundhole exactly like my Silvertone's. Yes, I'm aware that Harmony made Silvertone. There's also an odd discoloration on the fretboard which I have to take a picture of and post on the luthier section.
Ah, I didn't really even consider the 16th note. I meant that I don't think I've ever seen one where the "Harmony" script stood alone (on a uke anyway). Every one I can think of has the script on some sort of field or shield.
