This is a carbon fiber case for a screw bell double horn, made in China for Paxman UK. It fits the Paxman best but it will likely fit many other models. Includes backpack straps.
The carbon shell is tough and sleek. Its clear coat shows the distinctive fabric weave underneath. The interior has firm foam and velour-style fabric with small storage. A rigid divider and foam cone protect the bell flare. The hinge at the base is flexible so it takes some care to close the case properly, fitting the halves together at a sealed gasket before tightening the latches. The 4 latches look to be secure, but be aware that the latch metal is soft and they can be bent if not treated gently. That's the Achilles heel of this case: lightweight latches. (Every case has one problem, there is no perfect.) The a demo model case has a few marks on the latches and the exterior from use and from straightening the latch hooks. I found that a light polish with some auto polish or similar will rub out most scratches and marks from your travels, giving the case a bright shine again.
Atkinson Geyer does not fit, too large.
