285642 would be a Rola speaker made in the 42 week of 19x6 (you have to figure out which decade using other information).For additional speaker manufacturer codes, see Ted Weber's listing at Weber Speakers.
Any other single speed model (45/47/51) is prior to late 1963.To include a Leslie speaker or Hammond Tone Cabinet see the bottom of this page. Beginning in late 1935 and continuing to mid-1975, the archetypal instrument we think of when hearing the word "organ" was produced by the thousands.Please include an email address so I can contact you if I have a question. With a production history covering more than forty years, determining the exact manufacturing date of tonewheel Hammonds used to be difficult; new models were not introduced every year and production changes that were made were often subtle.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.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.
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.
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.
What follows is a breakdown of the more common parts and a description of their codes.
