Earlier there was some discussion of "monster" sousaphones in use. Since then I picked up my York sousaphone from having some minor work done. Here is a photo. This was made around 1925. It's not in perfect condition, but plays fairly well. The body may not be as large as some of the monster Conns that I have seen, but it has about a .740" bore and a 28" bell. The body is a little larger than my 20K. Just thought some might be interested.
