The LVT3 inherrited this arrangement and I would expect that the Armoured Snowmobile / Penguin did too. The Hydramatic gearbox used in Stuart had a reverse gear but the ones used in Chaffee and I believe LVT3 did not have a reverse gear, this was done in the 2f + 2r transfer box. This engine was also used in infantry landing craft but presumably marineised to some degree. One of the nice things with these engines is that the exhaust manifold was black vitreous enameled and bolted on with stainless bolts - Cadillac had their standards to uphold !
