I am unsure who made the case. It looks like a Pelican. But the latches aren't the typical Pelican style. Either way, its typical Pelican type quality - water proof and has the "vortex" pressure relief valve. Here are the dimensions;
11.75w x 8.25l x 3.5d - precut foam cutout
15.25w x 10.5l x 4.125d - bottom internal
15.25w x 10.5l x 2.0d - upper (lid) internal
Of course, the precut foam can be cut out more for a custom fit for your head. An electric kitchen knife works real well for this purpose. Just pull of the bottom of the precut foam, cut the sides to your spec, and away you go!!
$50 shipped. Thanks!
