This is a near mint double independent trigger bass trombone, not a single dent or mute mark on it, just minor lacquer wear on the slide contact points. Both valves work quickly and silently and the instrument blows very freely due to the open wrap. The slide is 10 out of 10. Also comes with additional tuning slide to allow it to play in Bb /F/Eb /G & Bb /F/D/Gb. This is a professional trombone, with much respect. See the following site for technical details: http://www.trevorjonesltd.co.uk/ybl613.htm See this ad for a recently sold virtually identical version. http://www.britishtrombonesociety.org/forum/ads_item.php?id=99&sid=399be57ec9dcc988d791dae0f67bb1ce My price is £995 and no offers please. The new equivalent price is £2800 after discounts. This is a serious bargain which (hopefully) won't hang around. No timewasters please.
