Dating ukuleles, banjos and mandolins
Guitars are the easy case. Ukuleles, banjos and mandolins mostly come with no dependable serial system, so a number stamped on one is often not a date. The decoder says “cannot tell” for them, and that is the honest result. This guide covers what to do instead.
Why the numbers are weak
Many makers of small instruments built for the mass market kept little or no record. Some numbered by model, some by batch, some not at all. Instruments were also sold under dealer or retailer names, so the name on the headstock may not be the maker. Where a numbering system did exist, the records often did not survive, and the tables in circulation were rebuilt from surviving examples.
Martin is the notable exception for its own ukuleles and mandolins, with separate charts that this tool does not yet include. See the About page for known gaps.
Where to look
- Labels. A paper label inside the body, visible with a torch through the soundhole, may carry a name, an address and a model. Addresses and trade names changed over time, so they bound a date range.
- Neck block and heel. Some numbers and pencil marks are written here. Treat them as part of the instrument’s history, with no assumption that they are dates.
- Headstock. Decals, inlays and shapes changed with fashion.
- Hardware. Tuners, tailpieces, banjo hoops, resonator style and tension hardware each have a period.
- Construction. Binding, bracing and the use of solid or laminated wood point to an era and a price tier.
What to record
Photograph the label, the neck block and any marks before you clean anything. Write down the exact wording on the label and note any address. A precise description lets someone else compare it with a catalogue, which is how these instruments are usually dated in practice.
What a date range looks like
For these instruments a sensible result is a decade or two, with the reasons. “Probably 1920s to 1930s, based on the label address and the tuner style” is a better note than a single year. The decoder uses the same approach for formats that carry no year: it says so and points to physical clues.
Silvertone, Kay and Harmony
Some retailer-branded instruments were built by one of several factories. Silvertone instruments were built by Danelectro, Harmony or Kay. Each has no published date code in this tool, so the brand page shows labels and features to check.
Check this next
Look through the soundhole with a torch for a paper label, and write down every word on it before you search for anything.
A date range for one of these instruments is an estimate, not a verdict. Nothing here values an instrument or checks that it is genuine.
