This primary Reynolds serial number sequence dates from 1936-1979 and includes all Reynolds instruments with the following exceptions: I believe that, while exact dates may never be able to be accurately verified for a specific serial number, the general progression of these lists is defensible and represents Reynolds instruments through the company’s history. Except for a fragment of Reynolds’ production data from 1964-1979 that is preserved in the Allied Band Supply catalog, I am not aware of any surviving official serial number records for Reynolds brass instruments.Īs such, the serial number lists compiled below have been based on the visual observation of engraving patterns and other instrument details that I’ve cross-referenced against catalog illustrations and other available historical information. Using serial numbers to identify the exact production dates of Reynolds instruments is inherently inaccurate given the lack of published records to corroborate with.
