Ran across this listing. Looks like it was sold and listing is gone. I did not think that they made the Low Bb baris in the S1 series. But I guess I was wrong. I was able from the grainy photo to verify tha S1 Bari style Eb-C cluster. Also , has the circular brace though it seems to have an extra piece on it.
