This flight case measures 37cm wide x 28cm deep (not including handle) x 14cm high externally. 

Internally, it would suit something up to, roughly, 32 x 24 x 10cm. As seen in the photos, it’s got a few external dints and bumps and the lower part of the sponge foam lining has been chopped up to suit a previous purpose. Otherwise it’s in good, solid order. The hinges and catches work well, but there’s no key for the locks.
