Original Conn 22B vintage Bb/A tuning slide that came with these early horns. This horn was built in 1927. Transposes to A automatically by turning small rotary valve; engages another small length of tubing to lower pitch by 1/2 step. In very good condition; one small dent and some tarnish that is very stubborn. Spit valve excellent, cork and spring fine. Looks like it was re-plated silver somewhere along the line. I have this complete original horn if you are interested. Just look at my other listing.
