The six-wheeled, amphibious Stalwart was produced between 1963 and 1971 by Alvis Cars (who were also responsible for the six-wheeled Saladin Armoured Car). The Stalwart, which served the British Army beginning in 1964, has a welded waterproof hull and a cab that is entered through twin hatches on the roof. The all-wheel-drive on land is powered by a Rolls-Royce 8-cylinder engine, and in water, it moves under vectored thrust water-jet propulsion units.
The Matchbox Alvis Stalwart was released in 1966 with white paint and BP Exploration labels on the sides. It can be found with yellow-hub wheels or green-hub wheels, as you see on my example, which was among my recent eBay score of 1960s Matchbox. Unfortunately, mine is missing the yellow plastic bed cover.
In 1979, the Alvis Stalwart was included (along with a Ford Heavy Wreck Truck) in the Matchbox Twin Pack TP-16, painted olive green and with black plastic wheels.
