This classic Greener double features a single brass bead sight on the matte rib, 3 inch chambers, and full chokes. The top of the rib is marked "W.W. GREENER. HAYMARKET LONDON & St MARY'S SQUARE, BIRMINGHAM, ENGLAND. WINNER AT THE LONDON GUN TRIALS, 1875, 1877, 1878 & 1879.". Both barrels feature 1 inch sections of very fine floral and scroll engraving forward of the breech, and on the rib extension. Just forward of the extension, the rib is engraved with a very detailed heron. The barrel flats have standard proofs and markings as well as the very interesting factory notation "CHICAGO EXHn. 1893". The scalloped box lock action features full coverage delicate floral scroll engraving with dog and bird scenes on the sides, relief carved fences, Greener patent safety toggle, a small gold inlaid crown on the break lever and dual triggers. Mounted on a fancy checkered splinter forearm and masterfully restocked with a matching round knob pistol grip stock with a horn forend tip insert and a checkered horn buttplate. Both the stock and forearm display a much fancier checkering design than seen on most Royal Grade shotguns, while the detail of the engraving reflects the same exhibition quality, all no doubt to showcase at the Exposition the ability of Greener's craftsmen that he employed to specifically work on his high grade G-Guns. Greener's exhibit at the 1893 Chicago Columbian Exposition featured rifles and shotguns of varying grades and styles. The exposition was a huge success for Greener and just a year later he was able to boast that "nine of the first 11 shots used Greener guns" at the 1894 US Grand Nationals. The exposition also represented a turning point for the city of Chicago after the great fire, and a symbol of the then emerging feeling of American Exceptionalism.
