I paid about £55 for this and it has only been out of my house once to transport a sub carbine AK with a side folding stock to a local indoor airgun range. It is in mint condition and still has the label on.

As gun cases go, this a very solid example. No flexing or bending. Tough and with provision for padlocks. Suitable for a submachine gun, a sub carbine rifle, lots of pistols and magazines, or, outside airsoft, any items that need to be protected from knocks when being transported. It has egg crate foam top and bottom, two snap lock fasteners and steel pin hinges. , 

Outer dimensions: 71cm long, 34cm wide

Inner dimensions:  68cm long, 28cm wide, thickness 10cm 

Can't find a box to put it in so I'll probably try to sell it to a bullpup owner down at my airgun range. But just in case anybody local is interested, it can be picked up from the Bolton area of Greater Manchester for £28. Sorry the last picture is out of focus.
