Here is a late model King 2106 Duo Gravis double-trigger bass in Bb/F/D. Probably from 1990 or so. Which means slightly wider slide, more contoured thumb triggers, and no beautiful engraving. It is in superb shape. Everything works well. Slide action is very good; valves have tons of compression; triggers are silent. Comes in the original Conn/King hard case. Plays like a dream.
