The normally numbered "Couturier Wizard" cornets I have placed in 1914.In 1926 the company name changed to York Band Instrument Company (S24), and the first such engraved instrument that I have recorded is numbered 87787, which now corresponds to the 1926 date. and granted Nov 6, 1928, and Jun 12, 1928, respectively.Instruments made after Carl Fischer took control of York are included, but obvious conflicts in numbers are confined to their own section.
For more information, go to the Detailed Record of York Instruments.This is further compounded by the existence several companies that have used the name "York" since then, including Boosey and Hawkes, the American company Brook Mays and the current manufacturer Schreiber & Keilwerth in Markneukirchen, Germany.Since Carl Fischer chose to outsource some York models and use assemblies from other companies under their control (such as Blessing), trying to make sense of anything not built in Grand Rapids has been compared to trying to herd cats.Few of the manufacturers produced instruments during the last 2-3 years of World War II.All of the manufacturers exhibit a dramatic growth in production immediately following World War II. They were created by taking the last number I have obtained in what seems to be an unbroken sequence of serial numbers (up to cornet 308783), and distributing them until the factory was closed in 1971, regardless of manufacturing source.
