HDY.{William Hardy}1/HY.{Tom Haldenby - Plant Engineer}24.9.34. SpectreCodename for Phantom III and Wraith Gearboxes. ------------------------- With regard to the gunmetal casting on the gearbox which houses the selector rod plungers and interlock, would you kindly let us know whether there is a suitable light alloy for this piece. There is the question of the plugs in the bores which are now sweated in. Would there be any satisfactory way of closing these holes apart from screwing and plugging? HDY.{William Hardy} | ||
