Off Topic Picture - 1962

[Mark in Rochester]

Looks like an m113 chassis...

It looks like a tank because the chassis is reworked from an Army M42 40-mm. gun carrier. A 500-hp supercharged Continental six speeds it along roads at 10 m.p.h., but there's also an electrical drive by which it creeps 15 feet per minute. It could wrench the concrete all off a test cell without grunting hard–drawbar pull is 85,000 pounds.
The cab, however, is nothing like a tank turret. It not only turns around and around, but moves up and down 15 feet on four stainless-steel legs (built like hydraulic auto lifts). These movements are precise but slow, for that cab weighs 50 tons.
The walls are made of foot-thick lead covered inside and out with half inch steel plates. The entrance hatch is a tight-fitting cork of lead directly over the operator's head. It alone weighs 7 1/2 tons.
The hatch offers the only way in or out.
