Anthony Peronti wasn’t messing around when he designed this baby carriage, a sheet-metal torpedo with welded fenders and a tanklike tread:

With the above described construction I have provided a baby carriage which will move easily and quietly over any type of surface and by virtue of the flexibility of the springs, curbstones, door-steps and other minor obstacles can be negotiated without tilting the body of the carriage and with a minimum of jarring or discomfort to the passenger.

He filed the patent in November 1945, so perhaps he’d been inspired by the battlefield.
