The only one I could definitely find with an outside throttle was ATSF #3463, which may be a 4-6-4 Hudson. Reading Railroad #214, a Pacific type has a frontend throttle, and looked very similar to the Mantua Pacific. As the original Mantua company was out of Pennsylvania, I would not be surprised if the model were based on the Reading steamer. In point of fact, most later steam locomotives equipped with superheaters were equipped with frontend throttles, as finer control was possible with the frontend unit.
