Here is the Brook Mays listing: https://www.brookmays.com/i--EUPHST1...ium-wCase.aspx
Listed as a "King" euphonium. Their web site listing for euphoniums basically sucks. This contributes to their suckiness. Another example is they have Willson compensators listed under non-compensating horns. This website is so badly done that it almost looks like it is not authentic. I would fire the current website dude and get their website in a little better order. It is horrible.
