Don't get too hung up on searching for temporal coordinates to the exclusion of the unit's real purpose as a musical instrument.Some of the component parts of Hammonds and Leslies have EIA codes printed on them.To help determine the manufacturing date of Hammond organs and Leslie speakers.
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.
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.
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.
The typewritten silver foil tags appeared in the mid to late 70's.
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.
285642 would be a Rola speaker made in the 42 week of 19x6 (you have to figure out which decade using other information).
