This extremely rare 20 gauge John Dickson & Son shotgun is identified by serial number on page 282 of Donald Dallas' "John Dickson & Son: The Round Action Gunmaker" along with its gauge, hammerless ejector action, and 28 inch barrels when it was originally sold on August 1, 1917. Blued steel barrels with single steel bead sight on the smooth, concave solid rib which is marked "JOHN DICKSON & SON. 63. PRINCES STREET. EDINBURGH", 2 1/2 inch chambers, and both London and Birmingham proofs on the flats. The famous John Dickson & Son round body boxlock action displays the "JOHN DICKSON & SON/PATENT" marking on either side and beautifully executed floral scroll engraving surrounding four exceptional game scenes. The game scenes consist of a trio pheasants feeding in a field on the left, three snipe in a marsh on the right, a single pheasant bedding down in a field on the underside, and three grouse in a highland lake scene on the underside. A grouse scene of a pointer is also features on the trigger guard and a single grouse on the top lever.
