Rare Early 1970's King 3B Concert Jazz Tenor Trombone with Cronkhite Gig Bag

Early 1970's King 3B Concert Jazz Tenor Trombone with included nearly-new Cronkhite cordura gig bag. King trombones from this era are widely sought-after. No mouthpiece included. General lacquer wear and mild scratches (as to be expected from a 50 year old instrument), but well-maintained and loved. Recently serviced and aligned, and slide action is a 7 or 8/10. Additional photos available upon request, and a pickup would be preferred; otherwise I can ship for $250 (covering large box, bubble wrap, packing peanuts, and fragile transit). Great horn for a jazz player and also great investment, as these will only go up in value over the years. Getting rid of to downsize for moving and I don't use this horn anymore.
