The estimated production curves for the YORK Band Instruments are based on instruments for which serial number and date of manufacture are known. In addition, an estimation of monthly output in the early part of the century and a correlation of serial numbers with patent dates which appear on certain York instruments has been taken into account. Six individual yearly production rates are plotted above, and it is projected that the closest estimate of the actual year of manufacture can be estimated by establishing a range of possible dates from these production curves. For example, an instrument with the serial number 28000 could have been made between the years 1904 and 1910, depending on the actual rate of production. It is believed that the yearly production rate of 2750 instruments comes the closest to meeting all the criteria used to establish this table, but variations in yearly production are not known, so the range of dates is probably the safest way to "guesstimate" the date of manufacture.
History
James Warren York was born on November 24, 1839, in Exeter, New Hampshire. He first worked for the Boston Musical Instrument Manufactory and in 1882 moved to Grand Rapids, Michigan where he first played in a music pit. He then owned his instrument manufacturing company until his retirement to California in 1917. He died in Los Angeles on February 9, 1927.
York manufactured a full line of brass instruments, both under its own name and proprietary brand names. York briefly participated in two partnerships, Smith & York (1883) and York & Holton (1885). In 1884 the company was known as J.W. York and Company. In recognition of his infant son Charles E. York, he renamed the company York & Son in 1887. York further changed the company's name to York & Sons in 1898 to include his other son, Frank W. York. Both sons were active with the company until about 1913.
In 1897, Alfred J. "Bill" Johnson became the company's foreman. In 1913, Johnson, along with John and James Duffy, formed a stockholding company, and when the York family relinquished all interest in the company in 1926, Johnson became a co-owner. The company was then known as the York Band Instrument Company. In December 1940, York was sold to Carl Fischer Musical Instruments and Johnson left the company. During World War II the company manufactured munitions. After the war, York produced student-line instruments. In 1971, Tolchin Instrument Company who then owned York, closed the factory. Proprietary rights were ultimately purchased in 1976 by Boosey & Hawkes.
