i Belive i seen a line of Flugles at Bidgemen's show lst nite being used by the Bushwackers...
But to answer the rest of you, Yes Crossmen did use them and sold them to Cav's.
There are a few corps that use them either as a 2 member or as a line section, they have been used as a replacement for the Coronet sound in a 3rd Sop capacity but it has a much throghtier sound that is more distinguished.. when played right in a song it could have a beautiful sound..
