51t

The Cooper T51 was a Formula One and Formula Two racing car designed by Owen Maddock and built by the Cooper Car Company for the 1959 Formula One season. The T51 earned a significant place in motor racing history when Jack Brabham drove the car to become the first driver to win the World Championship of Drivers with an engine mounted behind them, in 1959. The T51 was raced in several configurations by various entrants until 1963 and in all no less than 38 drivers were entered to drive T51s in Grand Prix races.

    Any idea where I can get a 51T 1/2x28 AAC muzzle device?

    Apparently AAC is still in limbo on so many fronts, I could not order a 51T muzzle device from my LGS. I've been scouring online and everywhere they say the devices are discontinued. Maybe someone here can find a source.
