Drum dating
Date a Ludwig or Yamaha drum from the serial or date code on it. Pick the maker, enter the code, and we read it against the maker’s own scheme.
Can't read a digit? Type ? in its place. Looked-up serials are kept, never tied to you. How it works
Type the serial or code from the instrument. We read it as you type.

How drums are dated
Yamaha stamps a letter date code at the front of the serial: from 1980 it gives the exact year and month. Ludwig’s badge serials read off Ludwig’s own published chart: the brass Keystone badges of 1963 to 1969 and the Blue-and-Olive badges that followed date year by year to 1972, then only in stretches, 1973 to 1976 and 1977 to 1979, because the chart groups those years. Ludwig applied its numbers out of order, so read every Ludwig year as approximate. Many vintage Ludwig shells also carry an interior date stamp inside the shell, which gives the exact date. If a digit on a worn badge will not read, type ? in its place and we try every digit.
Not every drum dates from its serial. Slingerland and Gretsch drum serials barely date at all, Rogers dates by badge era, and Pearl, most Tama and DW date by factory records or a born-on stamp inside the shell rather than a code. Where a serial cannot give a year, we say so. The hardware also helps: a potentiometer or other part with an EIA date code can be read with the pot and speaker code reader.
How sure is it
Every result carries its confidence. A Yamaha date code is exact; a Ludwig serial is a strong guide to within a year or two. Confirm a vintage Ludwig against the interior date stamp and the badge style.
