This Marcus Bonna COMPACT Quad Trumpet case is a bit smaller then the standard Quad. The compact case fits the 4 trumpets side by side rather then the standard which has 2 side by side and two stacked. If you are planning on carrying 2 trumpets and a flugel the quad standard is a better choice. It would be a bit too tight in the compact case. Only in stock in black nylon.
The comparable measurements are below:
Quad Case: 9 x 14 x 22 inches (flight regulation)
Compact Quad Case: 7,5 x 14 x 22 inches and the trumpets go side by side
