Organ Identification
It is not unusual to have situations where a new Hammond Organ owner may not readily be
able to identify the instrument he or she has. This page has been designed to help
individuals find the model and serial number plate on the Hammond Organ instrument. Also one
might make a determination by comparing to a picture of a unit or one might eliminate a model
possibility just by looking at a picture.
In the case of instruments made back in the mid to late 1930s, the serial plate probably has
the Hammond Instrument Company as the manufacturer name along with the serial number on a
metal plate. The plate is most often located on a shelf in the rear of the organ or in the
lower right hand corner of the cabinet in the back of the instrument. In the case where an
instrument has a rear cover, it may be necessary to carefully remove the cover and locate
the metal plate on the lower or upper shelf inside the organ.
The aforementioned locations were applicable for instruments manufactured from 1935 all the
way into the mid to late 1960's. Also up to that time, the serial and name plates
were either a metal or heavy plastic material.
In the late 1960s and on through the 1985 production, the year when the company went out of
business, the name plate including the model and serial number innformation along with the
Hammond Organ Company name and 4200 Diversey Avenue address in Chicago was located under the
lower keyboard assembly, acccessible and viewable from the lower front of the instrument.
The only exceptions would have been for the E-series, the H-series, X-66 and the X-77 series.
On these models the plate remained on the lower right hand corner of the rear of the instruments.
There are gaps in the representations shown below. We will try to fill the gaps as time goes on. We
would be thankful and honored to include in our identification section a picture from you of any
of the models that are missing. They are identified and are without picture above the model. Just e-mail
the picture,as an attachment, to us. Thanks in advance for your help and assistance. As this section
expands there will probably be some more instruments that we will not be able to come up with a suitable
photograph for. Keep checking us out; we would appreciate your help.
