This is a very interesting firearm. It is a Belgian-made single-shot folding shotgun chambered for the popular 20-gauge shell. It is chambered for 2 ¾ inch shells. The folding feature was intended to allow the owner to store the shotgun more easily or to carry it through the woods in a smaller format than a full-length gun. The shotgun bears Belgian proof markings on the bottom of the barrel. The release lever is serrated on the top to ease operation of the lever in messy conditions. The forearm is very small to allow the shotgun to fold properly. The case-hardened finish is a little worn which is understandable given the shotgun’s probable age. There is some light pitting on the receiver tang and in a few places on the barrel. It still retains most of its bluing, however. One interesting feature of the barrel is the shape. It is part octagonal and part round. Most gun owners/collectors are more familiar with this type of barrel being present on some lever-action and single-shot rifles. The bore is in excellent condition with a minor amount of plastic shell fowling present. The fixed choke is believed to be an improved cylinder choke.
