East Racing has an Argo JM19 prepared to the 3.5l Gp.C regulations that they race in Gp.C historic events. Now, this car does not look like your average JM19. I had thought Argo were out of business already when the 3.5l rules came along; but this car looks to be no simple conversion of a C2 chassis, but a "proper" 3.5l car. Is this a genuine Argo development, or a conversion?
