Thanks to the Electronics Industry Association (EIA) code conveniently placed on them by the manufacturer, many individual components can be dated to the year and week of production.Due to Hammond and Leslie purchasing components in large quantities, using these codes as definitive signposts will not produce an accurate "born on" date.

Additionally, some organs have been pieced together in order to get one working unit out of many; this will produce inconsistent and unlikely date code ranges.Just to get started, 21H's are 1951 to 1958, 22H's are 1958 to 1963, 122/142/147/145's are late 1963 and later.Any other single speed model (45/47/51) is prior to late 1963.Some of the entries on the age list show actual known production dates and can be used as markers to guage the quality of other entries around them.Until this work is published, the Age List will continue to function more or less as it has; a quasi-definitive source of this information and a registry of Hammond and Leslie product owners.Recently, the production data was found and there is no longer any need for guessing.

This information is being compiled, organized and edited into a soon to be released book that details all sorts of production and manufacturing information, including tables showing serial numbers and their date of production.

All available information must be taken as a whole, and, combined with some general tips and observations provided below, a narrow range of probable production years can be arrived at which in many cases will be accurate enough for most people's desires.

One thing to remember in this chronological quest is these instruments were built to be played, not (in most cases) to become museum pieces.

In the example shown, 190-7215 was made in the 15th week of 1972.

Earlier Leslie motors have a stamped four digit code.
