๐ Historical Perspective
This King 3BF Trombone, serial number 467245, dates from the early 1970s and features the distinctive โropyโ style bell engraving that many collectors associate with this period of King production. Models from this era are known for their lively response, classic King tonal color, and dependable slide action.
This example received a full professional shop service at The Brass Exchange, including chemical cleaning and complete mechanical inspection. The slide was outstandingโsmooth, fast, and well alignedโand the lacquer remained original and in remarkable condition for its age. Structurally it showed no signs of prior trauma, making it an excellent working example of a vintage 3BF.
The 3BF adds an F-attachment to the classic 3B platform, giving expanded lower range and convenient alternate positions without losing the familiar King feel. Many jazz and commercial players appreciate having that flexibility available for section work, pit orchestra playing, and big-band charts where quick position changes matter.
Examples like this early-1970s 3BF help illustrate why these instruments remain respected by players decades after production. They continue to offer the clarity, flexibility, and character that define the King sound.
The Brass Exchange has been serving brass players and collectors since 2010, preserving historically important instruments and helping musicians evaluate, trade, and consign vintage brass.
