The Hammond/Leslie Age Determination List |
The Hammond/Leslie Age Determination List
Last updated Sun Jul 6 17:46:34 2014 Version 4.169
Mission Statement
To help determine the manufacturing date of Hammond organs and Leslie
speakers.
Use this form if you would like to submit your Hammond
Organ for inclusion in these tables. When you hit the "Submit" button you will see a message
advising "Update Successful". Your information will be placed in a holding area for review and added
to the age list after acceptance. To include a Leslie speaker or Hammond Tone Cabinet see the
bottom of this page. Please include an email address so I can contact you if I have a question.
Discussion
- "How old is my Hammond organ and Leslie speaker?" Read on and you may
learn the answer! 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. 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.
-
- 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. 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. 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.
-
- 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. 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. Don't get too hung up on searching
for temporal coordinates to the exclusion of the unit's real purpose as a musical instrument.
-
Methodology
- Some of the component parts of Hammonds and Leslies have EIA codes printed on
them. What follows is a breakdown of the more common parts and a description of
their codes. Some specific examples are cited that can be used to provide assistance in
identifying the production date of similar components.
-
Tubes
- Many tubes have a date code on them. Tung-Sol 6550 tubes have
the following format: XXXYYWW, where XXX is the EIA manufacturer code, YY is the last two
digits of the year and WW is the number of the week in that year. 3227204 is a Tung-Sol
tube manufactured during the fourth week of 1972. Tung-Sol 6550 tubes made for other
companies (like RCA) have a four-digit date code only. 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.
In the example, 73-48 is the 48th week of 1973.
-
Capacitors
- Many capacitors have a date code on them, but some do not. 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. 6150 would be the fiftieth week of 1961.
-
Speakers
- 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. This may also be true for earlier units. 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. 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.
-
Motors
- Later Leslie motors have a sticker on them indicating their
manufacturing date. The formula is XXX-YYWW, where XXX is the manufacturer EIA code
(190 indicates General Instrument in the present example), YY is the last two digits of
the year of manufacture, and WW is the week of manufacture. In the example shown,
190-7215 was made in the 15th week of 1972. Earlier Leslie motors have a stamped
four digit code.
-
Leslie Cabinets
- 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. 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. 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. The new style Leslie
logo appeared in 1970, and cabinets made after then have particle board baffles rather
than all hardwood construction and are missing the instruction sheet formerly pasted to
the back. The code consists of 4 digits; the first 3 numbers are the Julian date, and the
last digit is the year. For example, model 25 serial #1522 has 1619 stamped on the baffle
identifying it was made on the 161st day of 1959.

Enumeration
Below is a compilation of Hammond organ serial numbers
and dates submitted by owners and other interested folks. There are discrepancies here,
so be prepared for some imprecision; it should get you within a year or two when combined
with the information above. Since I can't independently verify the
information provided this seems to be the best we can do.
Note: Organs produced after 1968 had a letter prefix
code in the serial number: A=1969, B=1970, C=1971, D=1972, E=1973. Sometime in mid-1973,
in the mid-200000's, Hammond dropped the prefix letter. this means half the organs built
in '73 and all '74/'75 organs have no letter code. Serial numbers began to take
on a surreal quality at this time, with higher serial numbers not necessarily representing newer units.
For example, A-xxxxx = 1969, B-(x)xxxxx = 1970, C-xxxxxx = 1971, D-xxxxxx = 1972, E-xxxxxx = 1973.
Organs previously in the Age List falling in the prefix group have been removed
since they readily admit their age.
Notes: Models produced in other countries had a different serial number system.
Confidence Level is an arbitrary rating from 0 to 100. 33 indicates wild guess, paper documentation
bill of sale, etc.; 66 indicates matching by using cabinet features list; 100 indicates looking at date
codes and cabinet features.
Units are located in the United States unless otherwise indicated.

Model A100 Series
(Manufactured from ~1959 through 1965)
Note: Model A105 continued to be
manufactured until January/February 1975.
-
Note: Around serial number 20000, Hammond assigned a block of serial numbers to the decorator cabinets in the
A-100 series (A-101/102/105/122/143 etc.). This has caused owners to wrongly attribute the age of their
instrument when based solely on the serial number, and consequently, many of the serial numbers reflected in the age
list for this group are probably in error. If your unit has a serial number in the 20000 to 30000 range you
must check date codes to get an accurate reading of its production date. Serial numbers after 30000 were reserved
for A-100 models only. When Hammond used up the decorator block of numbers they were reintegrated into the pool of
general A-100 numbers.
