This is a .460 bore horn with brass inners and soldered-on stockings. The taper is very gradual through the neckpipe and tuning slide crook. The bell is around 4" and it plays at A=440.
The garland is soldered in place, rather than being stretched and pressed as was originally done on period horns. It's a not perfect, but I think it maintains the vintage look you want from a sackbut.
I'm including a Conn mouthpiece that I modified to get the flat rim and sudden transition into the backbore. The bowl was partially filled with a copper/silver alloy, then machined out to a bowl and re-plated by Anderson. There's a bit of tarnish on the rim, but it will polish out.
The water key was removed and the hole was filled using a small brass disc and silver solder, then re-plated by Anderson.
What I like about this horn is that there are no compromises in bore. It was designed to have a small bore with a small taper. While it's not perfect, it's much closer to the style of an original sackbut than a cut-down Bundy, or some of the reproductions on the market today.
The case was an experiment. It works, but I gave up on the addition of fabric liner because it just wasn't working out as I wanted it to. The case itself was designed to carry arrows, and has a foam liner. The slide compartment works very well, but the part that holds the bell is rather crude and cave-man-ish. If you'd like, I can include a replacement for that section in plain foam, cut to fit the bell section. The fabric is held in place with spray adhesive and rubber cement.
