I do not think so. They are in early 1900's military uniforms. In the back you an see map pouches and web belts. Also they have the ubiquitous foot locker in back. It looks like it was taken in a military setting. Also the bassoon player has the neck strap. I do not think he would put it on just for posing with it. I could be wrong.
Another item in the file related to my theory that Conn experimented a lot with the wrap of the cylindrical tubing on these things. You hardly ever see two alike. (There are two alike in the Tuba Exchange historical collection, but they have sequential serial numbers.) I find the amount of variation surprising.
