When did Parker Bros. first catalog a Ventilated Rib on a double?
Hunter Arms introduced the Double Barrel Trap gun in 1920, and the 'Trap Package' included a flat beavertail forend (Schnabel forend available in 1922) with the reinforced barrel lug, Automatic Ejectors, Hunter One-Trigger, standard recoil pad, and two ivory sights. The ventilated rib on the Double Barrel Trap was introduced in 1925.
Francotte (imported by Von Lengerke & Detmold) and Greener
Single Barrel Trap guns were introduced in 1895 I believe with ventilated ribs. Lefever introduced a SBT with a solid rib in 1905, but Baker was the first major U.S. maker to offer a ventilated rib on their SBT in 1909.
The Prechtel SBT first appeared at the Cleveland Cartridge & Target Co. tournament in Cleveland, Ohio June 1897
