Otto Link Florida Straight Sig 5Here is a late 1960's possible early 70's Tone Edge tenor 5. This piece measures . 083" on my gauge. Over the years, the Tone Edge design has been changed many times. This era of production features a slim body, USA on the shank, a steep, long beak, a pronounced clamshell type baffle and horizontal pattern milling marks along the table and curve. This one is very clean, in very good original condition.
