Resources for Organ Restorers and Enthusiasts


The Estey Organ Museum does not provide appraisals of Estey instruments or related products. We suggest that you look at our Organ Classifieds page or on-line auction sites to determine the value of your item.

In addition, the Reed Organ Society website provides guidelines for determining the value of reed organs.


At this time, the Estey Organ Museum does not repair reed, pipe, or electronic organs. There are several reputable organ restorers in New England and throughout the country. The Reed Organ Society has member throughout the United States who specialize in this work. Contact the Estey Organ Museum for additional information.

You might find this 1886 Care and Adjustment of Estey Organs booklet useful as a reference.

Determining the Age of Estey Reed Organs

Determining the age of an Estey reed organ starts with identifying its serial number. Serial numbers are generally found on a paper label on the back of the instrument.

Each Estey reed organ was numbered as it was shipped out. By the time the company closed in the late 1950’s they had built over 521,000 reed organs.

Some serial number dates are known for certain:

  • No. 8,700 was shipped in May 1864
  • No. 100,000 was built in 1880
  • No. 250,000 in 1892
  • No. 350,000 in 1905
  • No. 500,000 in 1951

The exception was the Estey Virtuoso Organ. These organs were given special serial numbers. A few organs have been identified with lower serial numbers than dates of manufacture, perhaps indicating that they were not made consecutively.

Finding the Serial Number

Finding the serial number on Estey reed organs can be challenging. Ned Phoenix, an expert in reed organ restoration, has provided a guide for locating serial numbers on Estey reed organs and melodeons.

Occasionally the serial number on an older instrument is impossible to locate. If you are trying to determine the age of an organ with no serial number, please feel free to contact the museum for assistance. Make sure to include a photo of the organ.

Determining the Date of Manufacture

Once you have identified the serial number, you can use the Gellerman chart on the Reed Organ Society website to approximate the date of manufacture. This is just an estimate, but it will give you a good idea of when your Estey was built. Contact a professional appraiser if accuracy is essential.

Viewing the Gellerman Chart

R.F. Gellerman published a chart of Estey serial numbers in the Reed Organ Atlas.  Below are instructions for viewing this chart  on the Reed Organ Society website.

  1. Access the Gellerman pages on the Reed Organ Society website.
  2. Select Online Database to open the Reed Organ Database.
  3. Key in Estey as the reed organ manufacturer. The first Estey organ in the database will appear.
  4. In the Maker row of the chart, click on the Information on Maker link.  A chart of serial numbers with corresponding dates will appear.

Estey Pipe Organ Records

Pipe organs took longer to build than reed organs and created a greater amount of paperwork. Most of these records were destroyed when the company closed in 1960. However, we do have photo copies of the Shop Orders for about 2/3 of the organs. The Brattleboro Historical Society has access to most of the correspondence files for the pipe organs. The Estey Organ Museum has records on most pipe organs built and shipped.

We encourage you to contact the Estey Organ Museum for additional information on your Estey pipe organ.

Note that the Organ Historical Society maintains a database of pipe organs searchable by builder, date of installation, location, and opus number.
