This is a Shires TB47 which is a tenor slide .547 bore with a bass nickel crook. Comes with #3 leadpipe. Great action on this open-blowing slide (I wish my bass slide action was this good). Small amount of chrome wearing at stocking (pictures included upon request via email). I prefer to sell in New England without shipping, but I will ship if buyer pays. $750 (USD) OBO.
