W.W. Greener ~ Greener's GP ~ 12 Ga

The Greener GP (General Purpose) is a single-shot, 12-gauge shotgun built on a modified Martini action, renowned for its robust construction and simple, reliable operation. Produced primarily by W.W. Greener from 1922 to 1964 and later by Webley & Scott through the late 1970s, it originated from "riot guns" designed for British colonial police forces.
