This is a small lightweight fiberglass case for French horns with a screw bell flare. It is made by Marcus Bonna in Brazil. The MB7 has room to store a mute and a music stand (sold separately). The lid has a compartment for small storage and a sheet music pocket is located on the back side of the case. Accessories included are double backpack straps, a single shoulder strap, a mouthpiece pouch, and an ID tag.
Weight: 7 lbs, 8 oz
Several sizes are available. Most double horns will fit in the standard MB7.
If you've got a large body Geyer style, the MB7 XL model may fit better. A divider inside is moved slightly to the right top accommodate the larger diameter of the instrument.
The first three instrument photos show a Paxman Series 4 that fits just fine. The last two photos show a Hans Hoyer G10A, and the Hoyer body is too large to fit inside the curved support without some stress to the glue joint. For this horn the MB7 XL is the way.
A compact version of the case is also available. It's a few centimeters smaller in each dimension. It has a slightly larger storage compartment inside, but only has room for a stop mute. It also may not fit some instruments if the bell flare is tall. We don't yet have a list of horns to fit in the compact case.
