King 4BF Late 1970's Large Bore Tenor

King 4BF Sonorous made in the late 1970's.  This is a large bore tenor .547 with 8.5" Bell and Nickel silver handslide.  It's similar to a 3B, just a little bigger and takes large shank mouthpiece.  This horn has had full shop service and is in perfect playing condition, no dents, dings, great slide.  Lacquer wear over the entire instrument, will get patina eventually, will have a gorgeous vintage look once the brass turns with patina.  Original case.  Would be an excellent first horn with a trigger for an advancing younger player, or a great utility type horn for a lesson teacher, or for anyone looking for a 4B of this vintage.  No service needs to improve playability.  Case included.  In-stock.
