Bb Euphonium (American-bore baritone horn) by Harry B. Jay, Columbia model."Jay manufactured brass instruments from 1910 to 1946. Used Columbia as a trade name." The 1920 Jay catalog lists this exact horn, so it's safe to say this instrument is circa 1920.ready to play, accepts a medium shank (euro-shank) mouthpiece like a 51D for the original Willson 2900. Most tenor-shank trombone mouthpieces still fit, but go in almost all the way.Currently configured for modern pitch (A440) so you can successfully play it with other instruments. From the 1920 Jay Catalog, "Designed in low pitch with tuning slide and extra valve slides for high pitch." Since A440 is between the two pitch standards (435 - 452Hz), it plays well in tune when you pull the main slide out 1.5", #1 out 3/4", and #3 out 1" (for summer temps). Practically speaking, this design enables superior pitch adjustment for varying air temperatures, compared to modern brass instruments.Louis Armstrong's first decent trumpet was a Harry B Jay. Some historians speculate his sound on the Harry B Jay hastened the prominence of the trumpet.Condition:
