Briley custom deluxe aluminum guncase

I bought this through a on-line auction house and discovered it won't work to house my trap gun. Really nice case but it's actually made for a gun with sub gauge tubes ( three sets). It has one compartment for the tubes and another for the barrel and forend as well as the receiver. Inside dimensions are 32" long x 5.5 inches wide x 5 inches deep. $170.00 plus what ever the actual shipping cost's are from Michigan.
