Under the Gilles' leadership, there was a burst of design and engineering creativity at Hunter Arms; the following new guns or features were introduced in the 1920s:
1920: Double Barrel Trap Gun
1922: Large Schnabel Beavertail Forend with recoil lug
1924: Long Range Wild Fowl Gun with a larger frame, 3” chambers, and barrel reinforcing wedge (loop support)
1925: L.C. Smith Ventilated Rib designed by Gilles
1926: Ventilated Rib Double Barrel Gun “For Field and Trap Shooting”
1928: Skeet Upland Special – Pistol grip, Double Triggers, and Splinter FE
1929: Skeet Special – Straight, full, or half grip, Hunter One-Trigger, Automatic Ejector, and new “Streamline Beaver Tail Forend”
With all that excitement, it is certainly possible that a less-then-up-to-standards gun slipped out of the factory on a bad day.
It is my opinion that some cost savings production measures started in the depth of the depression.
