- Accordion and concertina owners identifying older instruments
- Worth noticing
- The site distinguishes public dating ranges from gaps in maker records, including private Hohner archives and Italian makers without public serial records.
Field notes
The lookup asks users to select a maker and instrument type before entering the serial number exactly as stamped, including letters and leading zeros. The homepage lists 25 makers, 506 dating ranges, and 19 published sources, and shows a Wheatstone sample dated from Horniman Museum factory ledgers. Its guides also explain limits in the records: the site says some Italian makers have no public serial records and Hohner’s archive is private.
