Only the "light" Twenty" had a gold trigger. My 1964 Belgium Browning Light Twenty has a gold trigger.
The A5 20 ga. was made in two models: Light 20, and Magnum 20. The Light twenty, sometimes just reffered to as a "Browning Twenty" was made from 1958-1976 in Belgium. The receivers are marked "Light Twenty" The Magnum version has a 3" chamber and was made in Belgium from 1967-1976. The receiver on this gun will say "Magnum Twenty" Other differences are the weight of the models
