However, by examining those components as a group one can determine that the instrument was produced no earlier than the latest date indicated by its component parts.In general, tubes appear to have had the shortest stock life and speakers the longest.Inside each Leslie produced after 1956, on the lower baffle, is a date code (sometimes hidden by the bass speaker).Here's how it works: You have to be able to date the Leslie within 10 years, which should be fairly easy.Even the above is fraught with some risk, as replacement parts used for repair or modification will occasionally skew the overall picture.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.Most of the tone generator wax and Mylar capacitors do, as well as pre- and power amplifier multi-section can electrolytic capacitors.The code typically takes the form of YYWW, where YY is the last two digits of the production year and WW is the production week. All of the speakers in Hammond organs, Hammond Tone Cabinets and Leslie cabinets dating from 1946 forward that I have seen have production date codes stamped on them. The coding scheme is XXXYWW where XXX is the company EIA code (Jensen = 220, Rola = 285, Heppner = 575), Y is the last digit of the production year, and WW is the production week.

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.In the example shown, 190-7215 was made in the 15th week of 1972.Earlier Leslie motors have a stamped four digit code.Tubes with "Hammond" silk screened on them typically have a code consisting of two pairs of numbers separated by a dash.The format is YY-WW, where YY is the last two digits of the year and WW is the number of the week in that year. Many capacitors have a date code on them, but some do not.

There are a number of visual cues: anything with a foil CBS ID tag is post 1966, anything with a metal tag is prior to 1966.
