I just picked up an old Harmony soprano ukulele. I’m trying to date it. It has a double ring around the soundhole. It has no label on the headstock, but it does have one inside the soundhole. The label is plain, rectangular, with “Harmony” in the typical company cursive in the middle and “Est 1892” centered underneath. (See the attachment.) No other markings. I’ve seen websites that discuss and illustrate Harmony’s various headstock labels over the years, but no soundhole labels are mentioned. I’ve seen online one other Harmony with the same sound hole label, but it has no information about its date. Thanks for whatever info you can provide.
