This is an original mouthpiece and ligature for the Hohner President alto saxophone. The seller claims that the ligature is silver plated.
According to the seller, this piece is from circa 1952, and that it was built by Julius Keilwerth. Supposedly JK supplied all the mouthpieces for his brother's saxophones at Hohner. I have not seen this confirmed anywhere else, so I am not stating this as a fact. This is just what the seller claimed in his eBay ad. Some independent research is required here, to see if this claim can be proven.
