The metal Selmers that Marcel Mule played had a slightly larger chamber than the modern one, but not by much. It's interesting since his tonal concept was quite a bit brighter than pretty much anyone else at the time, and the C* was the largest tip opening that they made. I've always wondered if he would have played a larger tip if one had been available.
