Guardian Double Canvas Motor Case The Heritage Collection is made in a classic design that combines a heavyweight waterproof laminated fabric with quality Leather. This results in a product that will be relied upon for generations. The Motorcases have been designed to keep your prized shotguns safe during transport in spaces that a traditional shotgun case would be awkward to fit. It achieves this by storing the barrel directly above the stock which also gives you plenty of room in a hidden compartment for your maintenance kits.
