Swanee-sax

This is a slide saxophone made entirely of silver-plated brass, with a simple design consisting of a straight conical tube with a bell flare that contains a box gutter with a slider shaft on the inside. The box has a small integral crook where a single-reed mouthpiece can be attached (mouthpiece missing), and a cork stopper on top (also missing). The slider is moved up-and-down along the box through a handheld piston, thus producing different pitches. This example is probably a Model B (lowest note) that has a compass of an octave plus four notes (B-F).
